2021-03-01T14:41:36Z ThreadRPCServer method=getbestblockhash user=dfid

After each cycle it seems the RPC connection to defid times out.

I did increase the timeouts via dfid.conf

[...]
rpctimeout=180

# debug
debug=mempool
debug=rpc

I am trying now with changing the timeout value on dfid as well as adding rpcservertimeout=1200 like I did on the btc-node and see if its helps.

Created PR for a possible solution.
#4

For reference I will re-open this issue.

@AltCoiFish
Did return AuthServiceProxy(url, timeout=240) solve the issue on your side?

Yes , its running now over 24h without any problems.
As described above, I also increased the timeout but I did this also prior to adding the timeout=240 .

Thanks for you replay.
So you ended up with the rpcservertimeout=1200 in bitcoind and defid?
Also in main.py you gave it 1200?

Did you recived as well the RPC error: -25: Min anchor quorum was not reached! ?

This is due to #6

Hi @AltCoiFish
I still have this issue.
I changed the rpcservertimeout in defi.conf. Also I adjusted the main.py with timeout=240 as you stated in you merge request.
You were refering to a other time out in the first post, you mean the general connection timeout in the defi.conf?

 -timeout=<n>
       Specify connection timeout in milliseconds (minimum: 1, default: 5000)

Realy strange, my setup isn't stable.

[dell1503]

I did again a clean defid Blockchain download (remove all existing data in .defi/* expect the ther conf) overnight. the Error: [Errno 32] Broken pipe error did disappear, no other changes, no config change nothing.

Not sure if you are aware that you can also create an anchor manually following the guide below. Please make sure you are on DeFiChain 1.5.1 that has just been released. When upgrading to 1.5.1 please start the client with -spv_resync or add spv_resync=1 in your .defi folder, you can check the sync status with the RPC command spv_syncstatus.

DeFiChain 1.5.1 Release

https://github.com/DeFiCh/ain/releases/tag/v1.5.1

I'll raise your reported issue with the team and get someone to try and recreate the issue.

Thank you very much, my node is running on 1.5.1.
If needed I cann provide more logs ore even access to the system. You can also reach out to me on Telegram, if a faster exchange is required.

So in the morning the system was running. I then decide to keep in in the loop running with :
./main.py --config ./config.toml --repeat 3600
It looks to me, that it some time it run, sometimes I recived
RPC error: -25: Min anchor quorum was not reached!
or
Error: [Errno 32] Broken pipe

I keep it running and will so how is doing.
