Issue apache2 is crashing frequently

[FelixB]

hey there.

my apache2 service is crashing frequently, and is not able to start it selfs frequently

when it happens i need to kill pid's which are blocking the socket needed and then start apache2 again.

but why?

Hello FelixB,

Will you share your Apache log so that I can better understand the nature of the problem?

what do you think?

 

[Pentarou]

It seems that adres on port 7080 is already in use, causing the problem, you have to check your configuration file.

 

[Brujo]

It seems apache was not stopped completely or started to early. which settings do you have in Apache Restart Interval in Tools & Settings > Apache Web Server? and do you have the Watchdog extension installed and enabled?

should I really make changes to a conf file? I ask because apache2 is installed and managed by Plesk.. I think if I change the config file myself it would be a risk for Plesk...

Well the settings are:

Apache restart interval -> 0
Piped logs -> deactivated
MPM Mode -> Prefork

some modules are enabled... need to list all here?

See also: How to enable/disable graceful restart for Apache?

should I try to enable this?

 

[Brujo]

[FelixB]
