Cronjob causes NGINX 502

[sdmx80]

Hello!

Tonight, for the second time in a row, my server crashed because of a cron job. All websites displayed a NGINX 502 error.

This is the error message that was sent to me:

Can you tell me what I need to reconfigure to stop my server from crashing?

Thank you very much in advance!

@sdmx80,

Did we not already resolve this within this topic thread: http://talk.plesk.com/threads/nginx-502-error.335745

Check memory settings and adjust them according to point b) in my post http://talk.plesk.com/threads/nginx-502-error.335745/page-2#post-791020.

Another possible culprit is that a lot of tasks are running at approximately 03:25 and you can prevent that by changing the time of other cronjobs, such as scheduled backups.

Just let me know....

Regards....
