Looks like towards the end of the test the QPS for some types of transactions dropped to 0. And the we also failed to download the debug.zip.
@nvanbenschoten have you seen this before?

The last two failures (on release-19.1 both) show the transport is closing error.
I've looked into the last one. It looks like the cluster became very unhappy at the end. Node 1 has this:

W190612 06:03:38.732203 158527 storage/intentresolver/intent_resolver.go:822  [n1,s1,r51/1:/Table/60{-/1/405/5}] failed to gc transaction record: could not GC completed transaction anchored at /Table/60/1/80/8/0: context canceled

and then nothing for 6 minutes and then

W190612 06:09:03.748990 374 storage/store.go:3704  [n1,s1,r1114/1:/Table/59/1/59{6/7/4…-8/6/1…}] handle raft ready: 3.0s [processed=0]

This range is likely unavailable.

And then tones of ctx canceled and network errors.

The other nodes have network errors starting around 06:03.

There's also a heap profile (on n1) at 6:03 that shows a lots of memory tied up in ScanResponses:

This line

have been waiting 321.54s for proposing command ResolveIntent

is actually pretty interesting because it's supposed to only ever print times that are close to ~10s:

cockroach/pkg/storage/replica_write.go

Lines 204 to 206 in 7e2ceae

case <-slowTimer.C:
slowTimer.Read = true
log.Warningf(ctx, `have been waiting %.2fs for proposing command %s.

cockroach/pkg/storage/replica_write.go

Lines 176 to 179 in 7e2ceae

slowTimer := timeutil.NewTimer()
defer slowTimer.Stop()
slowTimer.Reset(base.SlowRequestThreshold)
tBegin := timeutil.Now()

The fact that it took more than 30x that does suggest that something horrible happened to the machine. The CPU seems to be working pretty hard in the minutes leading up to the failure

12 06:03:32.819717 472 server/status/runtime.go:500 [n1] runtime stats: 13 GiB RSS, 4220 goroutines, 7.6 GiB/223 MiB/8.3 GiB GO alloc/idle/total, 3.6 GiB/4.3 GiB CGO alloc/total, 10351.9 CGO/sec, 1513.2/12.8 %(u/s)time, 0.0 %gc (2x), 396 MiB/38 MiB (r/w)net

"1513.2% utime" basically means the 16 cpus are maxing out. But still, I think this is already part of the downfall here, and I can't imagine overloading a machine to the point where lots of goroutines don't get scheduled for 300s. There's nothing in dmesg, but I found this in sysctl:

I tried googling for that message but with zero success. The kernel here is

^- anyway, this udev message doesn't seem like something we could trigger with a bug in crdb. Maybe the vm was "live" migrated?
