Dmitri Pavlov commented on KAFKA-17704:
---------------------------------------
That is another log snippet
!image-2024-10-08-19-10-13-215.png!
Changing the creds every 2 minutes.
[2024-10-07 11:45:11,652] - new TTL cycle starts
[2024-10-07 11:45:11,783] - "Starting task" messages.
I can see form the Mongodb audit, the username is correct.
------creds got changed here at ~ 11:46
[2024-10-07 11:47:11,793] - new TTL cycle starts.
Do not see tasks restarted after that. Stale creds are in use. Mongo audit
shows old creds are being used. Not always like that, sometimes.

> This is related to https://issues.apache.org/jira/browse/KAFKA-9228 and
> https://issues.apache.org/jira/browse/KAFKA-17627 but in single node instance
> and only related to credentials (as far as we know currently), so maybe
> something else is in play?
> In some cases, when TTL is used with a single node, passwords are not passed
> properly.
> In the "logstoupload.log" file you can see that at 09:14 the password does
> not get change, but at 09:24 it does get changed.
> We are able to "reliably" reproduce this in prod-like environment where this
> log comes from in Kubernetes, but we have only captured this "race condition"
> in test rarely where we are not using Kubernetes. We have seen it without
> Kubernetes though.
> We hope to provide something more reproducible next week, but perhaps
> uploading this "full" log will allow you to guide us so we can make this more
> reproducible.
