Plesk Web Server service is down

Hello,

Almost everyday my server goes down. Watchdog monitor log has the records:
[CET Nov 24 00:34:20] HTTP: error receiving data -- Resource temporarily unavailable
[CET Nov 24 00:34:20] 'plesk_apache' failed protocol test [HTTP] at INET[localhost:8443]
[CET Nov 24 00:34:21] 'plesk_apache' trying to restart
[CET Nov 24 00:34:22] 'plesk_apache' stop: /usr/local/psa/admin/bin/httpsdctl
[CET Nov 24 00:34:24] 'plesk_apache' start: /usr/local/psa/admin/bin/httpsdctl
[CET Nov 24 00:39:33] 'plesk_apache' connection passed

Is there a way to know what causes that problem?

Thanks,
Igor.
 
it is known problem caused by small connection timeout in watchdog settings (5 seconds) which may cause Watchdog detect apche down on busy systems.

By default Watchdog expects services to respond within 5 seconds. So I suggest you to go to
Modules > Watchdog > apache

and change 'Connection timeout' parameter from 5 to a larger value, e.g. 20.

That usually eliminates such problems. If it will not help, try to disable watchdog (because apache itself works fine).
 
Thanks for your answer.
I set apache and Plesk Web Server modules to 20 secs...
/usr/local/psa/admin/bin/httpsdctl - in the settings that command is for Plesk Web Server modules.
I will wait a few days and see if the server works fine.

Thanks,
Igor.
