backend_clean_cache get's stuck every night

Any ideas why backend_clean_cache cron job get's stuck every night? Is there a way to debug what causes it to get stuck?

Same for me. v2.3.4-p2

Did you find a reason why this occurs by any chance? Will report back here if I resolve it.

Re: backend_clean_cache get's stuck every night

I managed to fix this by adding this to env.php:

 

'queue' => [
'consumers_wait_for_messages' => 0
],

 

This was suggested somewhere. Mysteriously this only worked for a while and then the problem appeared again and I have not yet been able to fix this.

OK, think I have this sorted, in my instance anyway.

After a forced server reboot, looks like a cron job wasn't registered as completed, leaving it in limbo.

 

Running the following command in SSH showed a process running which was days old, they should only be minutes, hours at most.

ps aux | grep -i cron

 

Kill the process and truncate the cron_schedule table.

kill -9 [PID]

Issue came back. Sunday night, same time as week previous.

It's a recognised problem and has apparently been resolved on v2.4.1 which doesn't help when you've just got all extensions working and stable on a 2.3 release......
