Issue Apache sporadically shuts down

[Eirik Sikveland]

Hi!

I have a strange issue I cannot solve.
The Apache and Nginx service stops automatically every 1 week (7 days) in this case every Sunday morning (03:30 ish)

I then have to go into Plesk panel and start the services again.

The error logs don't tell me much.

[Sun Oct 23 03:39:29.755335 2016] [mpm_event:notice] [pid 11887:tid 140190696106048] AH00493: SIGUSR1 received. Doing graceful restart
[Sun Oct 23 03:39:30.087421 2016] [core:notice] [pid 11887] AH00060: seg fault or similar nasty error detected in the parent process
[Sun Oct 23 03:39:38.504782 2016] [fcgid:error] [pid 2498:tid 140190696106048] FastCGI process 16094 still did not exit, terminating forcefully

Any help is much appreciated

Hi Eirik Sikveland,

pls. consider to use "mpm-prefork" instead of "mpm-event", due to the fact that it works much better with "php-fpm" and additional installed apache - modules.

Alright, thanks, changed it to prefork. Do you think that would solve the issue?

I think than mpm-event is not a problem, if nginx also stop working.

Maybe you have any issue whit memory ?

I don't think so. This is a dedicated server with 16GB of ram.
Also according to the health monitor it was using about 450MB at the shutdown.

Hi

You need check apache config, also check logs, nginx main errorlog, apache main errorlog and order system logs

If this just happen each seven days

seg fault or similar nasty error detected in the parent process

maybe logrotate can cause seg fault when lock apache and try restart it but not start.
