Pruning extra revisions fail [3.7.45]:

[DavidKabelitz]

What happened?

Hi,
we have about 300 errors a day at the queue manager. Always related to different entries but always the same error message.

Not sure what the problem is.

Thanks David

Try searching through storage/logs/queue.log (and any other queue.log.X files) for that error. Does it show up? If so please post the full stack trace that follows it.

[DavidKabelitz]

Yes it's there:

2022-06-27 17:48:31 [-][-][-][info][craft\queue\QueueLogBehavior::beforeExec] [1976457] Pruning extra revisions (attempt: 1, pid: 21062) - Started 2022-06-27 17:48:34 [-][-][-][error][craft\queue\QueueLogBehavior::afterError] [1976457] Pruning extra revisions (attempt: 1, pid: 21062) - Error (time: 3.084s): Unable to acquire a lock for file "/var/www/craft/storage/logs/cloudflare.log".

or do you need the whole file? It's 8MB big

[brandonkelly]

I just need a stack trace. Is there one that follows the log you posted? If not try searching for other instances of the error message.

[DavidKabelitz]

it's always just like that:
2022-06-26 12:13:19 [-][-][-][info][craft\queue\QueueLogBehavior::beforeExec] [1971338] Pruning extra revisions (attempt: 1, pid: 15663) - Started 2022-06-26 12:13:22 [-][-][-][error][craft\queue\QueueLogBehavior::afterError] [1971338] Pruning extra revisions (attempt: 1, pid: 15663) - Error (time: 3.083s): Unable to acquire a lock for file "/var/www/craft/storage/logs/cloudflare.log".

[DavidKabelitz]

just to inform you...after restarting all these errors again it works and they are gone. So looks like a timing issue ...

[angrybrad]

@DavidKabelitz do you have multiple queue runners processing the queue or just one? Is this in a load-balanced environment?

[DavidKabelitz]

@angrybrad yes we are running on kubernetes with multiple pods and also a load balancer

[angrybrad]

@DavidKabelitz How are the queue runner(s) set up? Using Craft's default web-based queue runner, so each pod ends up being a queue runner? Or is there a dedicated pod just for deamonizing craft to process the queue?

[DavidKabelitz]

Yes it's the default web based queue runner.
In that case we solved it and removed the queue runner cause we already had cron jobs running with schedules.

su www-data -c "/usr/local/bin/php /var/www/craft/craft queue/run"

So for a better / clean setup a dedicated pod for the queue would be the solution?
