Plesk 12.5 causes apache restart caught SIGTERM, shutting down

[CrK01]

Hello,

my environment:
- Centos 6.7
- Kernel 2.6.32-573.7.1.el6.x86_64
- 24 GB RAM , 10 CPU , plenty resources ( low load average, all stable, 8 GB empty ram )
- Plesk: 12.5.30 Update #3,

Problem:

Everytime we go to plesk and click in "HOME" button, plesk kills apache and all is restarting ( so webs are restarting too, causing disconnections when navigating )

No problems viewing websites or other buttons, we can reproduce-it :

All ok , it's restarting ( plesk response is a bit slow going to home ). If we click in "home" , It's restarting again.

Thanks,

Ok , this is caused by Mod_security. If I enable plesk's mod_security , apache process is restarting everytime you enter plesk HOME.

If I disable mod_security , problem solved ( bad and insecure workaround )

Hi @CrK01!

The issue is fixed in Plesk 12.5 MU#4. It was published today. Try to run update.
