MySQL CPU & Memory Usage problem after Plesk Update to 11.5.30

[omuzdas]

After Plesk Updated to 11.5.30 we encounter a problem with the mysql. MySQL CPU usage always over 100% and ram usage increasing in a ladder pattern shown below.

There is no load on server. The graph below indicates that the date of problem encountered matches with the plesk update on my server (11.5.30 Update #38, last updated at Mar 28, 2014 06:50 AM)

I've made a deep research about that problem but could not find any solution.

I suggest you contact Parallels Support Team. They will investigate and fix this issue directly on your server. It is really difficult to find a reason in scope of forum discussion.

can you check task manager and go to procees tab, let us know which process is taking maximum utilization?
