⚠️ Before submitting, please verify the following: ⚠️

This is a bug, not a question or a configuration issue.
This issue is not already reported on Github (I've searched it).
Nextcloud Server and Desktop Client are up to date. See Server Maintenance and Release Schedule and Desktop Releases for supported versions.
I agree to follow Nextcloud's Code of Conduct

Bug description

Briefly, the client is locking up, repeatably. Locking up includes not responding to an open from the dock, locking up context menus in the windows shell and only responding to a task-manager kill. If the window is open, it locks up showing with "0B of 4.1MB file 1 of 34" or "7B of 4.1MB file 1 of 34"

Pertinent points:

I started with an old version of the desktop client (version lost). I upgraded to 3.6.7 (?) and then to a daily release 3.6.50 (grabbed 2022-12-06). All versions exhibit the same behaviour.
Nextcloud is up-to-date. No changes there (is in production).
if I add files to the local store, those files are uploaded, then this bug manifests.
It was stopping on one file in the local root (of the nextcloud) folder. "langs.xml" I didn't need that file, so I removed it. No change (found this with the client logs).
I also found all files renamed with conflict in them. I resolved those conflicts. No change.
The client logs stop mostly on the same file, but sometimes a different file.

Extra diagnostic points (not my first bug report):

computer rebooted, disk CHKDSK'd. client restarted multiple times. Behaviour is repeatable
logs created, but an awful lot of non-opaque information in them. Would prefer to share privately or to cut out small sections.
no other users of same nextcloud affected.
no errors in nextcloud server log
I tried removing files the log stopped on. Did not help.
I tried removing all the .db files in the root ... causing a complete resync. Did not help.

Steps to reproduce

Start nextcloud, wait. Obviously, not for you. This is 100% repeatable on my system. Nextcloud is effectively not working until fixed. I'm not sure what's causing it.

Expected behavior

Nextcloud doesn't lock up?

Which files are affected by this bug

langs.xml

Just saying that I chopped the bottom of the client log... and sanitized it. Feel free to ask for more, but I'd prefer that to be somewhat private.

to test that this wasn't a filesystem thing, I ran the following in L4W (Linux for windows) in the root of the nextcloud directory:

find . -type f -ls -exec cat "{}" >/dev/null ;

... which completed without error.

Similar with me, but Nextcloud goes completely unresponsive. I can’t open anything, and it just says “syncing” but without using bandwidth.

EDIT: Updated to the 3.6.3 Client which released some minutes ago, same issue.

EDIT2: While the Nextcloud client is started i am not able to open the Windows Explorer. Only when I close nextcloud via the Task Manager does it open.

joe-eklund · 2022-12-12T00:14:22Z

I also just started running into this issue. :( Same problem on both 3.6.2 and 3.6.4.

Edit: I updated my Nextcloud instance to the newest 24 version and my client version to 3.6.4. I then removed the sync, readded it, and resynced all the files. Seems to be working for now.

Obi-Wahn · 2022-12-13T08:03:30Z

Same problem with different Nextcloud client versions and windows 11 on my laptop.

Edit: On my "old" Windows 10 Desktop with Version 3.6.4 and the same server everything is fine...

tomdereub · 2022-12-14T00:39:57Z

Hi, I found a workaround here : #4106
Removing speed limits has solved the problem in my case (windows 10, desktop 3.6.4, server 25.02). Then I put speed limits again and it seems it's working normally...

Edit : the bug comes back, so the only way for me to get it working normally is to keep no speed limits.

Nordiii · 2022-12-14T08:04:35Z

Yes deleting this block from the nextcloud.cfg indeed fixed the issue for me:

[BWLimit]
downloadLimit=80
uploadLimit=10
useDownloadLimit=0
useUploadLimit=-1

Obi-Wahn · 2022-12-15T21:17:42Z

Yes, no speed limits fixed the issue for me too.

zBeeble42 · 2022-12-15T21:50:29Z

OP here ... so this is a workaround ... but not an acceptable one. Needs to be fixed.

I was able to start the client and just turn off the limit --- in my case, getting to the sync failure takes most of a minute. So I suppose doing it this way depends on your setup.

tomdereub · 2022-12-19T10:18:25Z

I got the problem with all computers of my company (30 persons), and with some others linked to my personal server. Seems to be related to the update to nextcloud 25, the bug appears with various versions of nextcloud desktop. It is systematic if speed limits has been set.
The fact that it blocks windows explorer is really annoying, and it's hard to debug if you don't find this issue on github. People try unsuccessfully to re-install nextcloud, to restart synchronisation from scratch (with risk of data loss for non-synced files), etc...
Even if there is a workaround, I think it's a major issue that should be quickly solved. I still see the "0. Needs triage" label, I think it's time to approve this bug and switch to "1. To develop".

joe-eklund · 2022-12-19T22:15:20Z

Well looks like the issue has returned for me. Seems like it only worked for about a week and now I'm stuck on preparing for sync again.

skytux · 2023-01-02T05:51:22Z

Looks similar than my issue.

System & client version:
################## "Nextcloud" locale: "en_150" ui_lang: QVariant(Invalid) version: "3.6.4stable-Win64 (build 20221208)" os: "Windows 10 Version 2009"

Conditions:

So it seems to happen for files between 1 byte to 999,999 bytes.

I tried to trace the bug, using some debug tools:

I add a PDF file with some contents (203,536 bytes).
The file gets read by a nextcloud.exe child thread (log + procmon)
procmon shows it by chunks of 16,384 bytes until EOF, but tries to read more from it several times. + queries some metadata.

MD5 hash is computed according to the log file.
nextcloud.exe child thread opens the file one last time (without any further operation with it). Stack trace is:

Last log messages before it freezes:
[ OCC::CookieJar::cookiesForUrl ]: QUrl("[...]/remote.php/dav/bulk") requests: (QNetworkCookie [...] OCC::PutMultiFileJob created for "https://[...]" + "" "OCC::BulkPropagatorJob"
(libsync\abstractnetworkjob.cpp:361)

950 bytes data is sent through TCP to NextCloud server (seen by procmon. - Not my server - I don't have logs for it)
Now nextcloud.exe UI is frozen, eating 100% CPU of one core
explorer.exe UI also gets frozen!
Now, if I delete the previously added file, UI stays frozen and eating CPU, but 1 new line appears in log file:
[ debug nextcloud.gui.folderwatcher C:\Users\sysadmin\AppData\Local\Temp\2\windows-12824\client-building\desktop\src\gui\folderwatcher_win.cpp:160 ] [ OCC::WatcherThread::watchChanges ]: Skipping syncing of "C:/path_to_folder_where_is_the_tested_file

I want to have a closer look on what's going on in the main thread stack, using procexp.exe:

After hitting "Refresh" several times, it looks like being stuck in this function: Qt5Network.dll!QHttpMultiPart::boundary+0x8b7

Here what happens in logs with 0 byte file creation: https://pastebin.com/GiKcqa4p
Which seems OK.
Using SHA1 checksum though, not MD5 as when it crashes.
This is called only here:

Both do that before:

libsync\owncloudpropagator.cpp:1285 ]: scheduleSelfOrChild OCC::PropagatorJob::NotYetStarted pending uploads 0 subjobs state OCC::PropagatorJob::NotYetStarted

There might be some kind of condition to decide weather to use bulk upload mode or not.
The bulk one seems to be broken for files < 1,000,000 bytes.

skytux · 2023-01-02T07:53:05Z

The issue seems to dissapear when disabling the Upload bandwidth limit.
Download might be left be on. But might be a problem to retrieve small files. Can't test easily now.

I imagine something like the bandwidth limiting feature not working well in bulk mode - and/or with small files.

stesee · 2023-01-15T20:25:18Z

Steps need to be done if you are affected by the bug:

Kill running Nextcloud client (e.g. using taskmanager)
Edit %APPDATA%\Nextcloud\nextcloud.cfg - remove BWLimit section

Yes deleting this block from the nextcloud.cfg indeed fixed the issue for me:
[BWLimit]
downloadLimit=80
uploadLimit=10
useDownloadLimit=0
useUploadLimit=-1

Start nextcloud client again
Dont touch your bandwidth settings until this bug has been fixed

nfrawley93 · 2023-01-19T03:40:16Z

@stesee a faster way on is actually just turning off Wifi so Nextcloud never gets to the "sync" part. Then you can still open the GUI and turn off throttling. (I needed a slightly simpler way for some of my users to understand)

You still need to kill the client in task manager first though to un-freeze it.

Kill Nextcloud client
Turn of Wifi or Ethernet (manually or software)
Start Nextcloud and turn off throttling bandwidth
Turn on Wifi or Ethernet

What an frustrating issue. I have throttling on so I don't over saturate my network every time a large file is uploaded.

Can't believe this isn't a higher priority.

Tublick · 2023-01-27T11:00:56Z

had the same issue but updating the Windowsclient to 3.6.6 (from 3.4.0) had solved the problem for me.

mlazzarotto · 2023-02-22T09:31:25Z

Still happening on 3.7.3. Nextcloud clients uses a lot of cpu and the computer begins overheating. Left-clicking or right-clicking on the tray icon does nothing, and the tray icon is the 'sync in progress' one.

Malspherus · 2023-03-13T13:30:44Z

I had the same issue with the windows client after updating the server to v25 (more details here). Disabling the upload bandwidth limit worked for me too, but the update to client v3.7.4 alone wasn't enough either. As an additional workaround the sync can be disabled for folders containing specific files, for me .lnk-files among others caused the crash.

Ericchi · 2023-04-03T21:03:45Z

I have the same exact problem on MacOS. Tried every possible fix until I remembered that I have recently set an upload limit. Removing it fixed the issue. Please, fix it. It's really important to me because I have a poor connection that can't keep up and is easily saturated whenever I upload a file unless I set an upload limit.

silen72 · 2023-04-17T08:45:09Z

Still happening on 3.8.0. Tested on Windows 10. Besides being completely unresponsive, it also seems to add significant lag to using the windows explorer.
