Issue Random Server Reboots/Crashes with plesk

[afterxleep]

I've been running 10.4 for several years on a server (CentOS 5.4) without any issues, but suddenly today, the server (a Xen based VPS) started rebooting suddenly just after sending your username/password to login.

It also seems to be crashing on any plesk/bin command line utils.

I've restored backups and discarded a hardware issue my moving VPS to other parent with no luck. There are no kernel crash logs that evidence driver problems or something close to that.

Any ideas?

Thanks,

D

The main Plesk logs are

• Error log: /var/log/sw-cp-server/error_log and /var/log/sw-cp-server/sw-engine.log
• Panel log: /usr/local/psa/admin/logs/panel.log

Have you checked them at least?

Thanks for the answer. I did check them but could not find anything relevant. I will try a fresh OS install+plesk and then restoring backups to see if that fixes the issue.

If that does not work I'll restore the server as it was and check those in detail.

Thanks!

Hi Igor.

These are the logs with errors. After throwing that error, the server reboots itself (like a reset).

From the error, you would assume mysql is down, or the sock file does not exists, but I checked both.

This started happening on CentOS 5.6 and is happening on a fresh plesk install.

There is really something wrong with MySQL. I would suggest you try to restart it and check MySQL logs.

Did you ever make progress on this. So funny this started November 18th, 2016 for me.

Noup. got tired after several days debugging with no luck. I wiped down the whole thing, installed a fresh copy of plesk and restored a backup.

Thanks for your quick response. I did the same course of action...I built a new box with latest version of plesk and migrated the 60 sites over. It was a pain and took me 16 hours to do it, but glad to be off plesk 10 and that server. Was an action item for over a year now....this finally was the last straw.

Thanks again!
