Issue Steady increase of ram usage until server crash (by watchDog stats)

[fabiodisconzi]

Hi to all, I am new to the forum and also to server management.
I own a dedicated server with PLESK installed.
Some weeks ago I activated the WatchDog extension.

The night of sunday 24th Jun something strange happened. Ram usage started to climb up to the server crash. This morning (25th of Jun) I was not able to login to the plesk, neither to the repair kit.
I resolved the issue by restarting the servir via SSH.

What could be the cause of the steady increase of ram usage?
Thanks,
Fabio

I would advise you to check all the cron tasks planned for the time coinciding with the beginning of this RAM increasing process.
