plesk_agent_manager high load

[pcsousa]

Hello, since yesterday I've seen this process on first position at top using 90 - 98% cpu.
I've already kill it and it back again.

Do you know whatcould this be?

Thank you!

Process:

Same problem after upgrading from 9.5.2 to 9.5.4

Can somebody tell me exactly what is this "plesk_agent_manager"?

The reason I had a very busy mail server that was running fine for well over a year but after an upgrade to 9.5.4 it has really slowed days. After days of troubleshooting I have finally managed to correlate this process 'plesk_agent_server' with the high CPU.

It seems that this process launches more child processes which combined slows down the server. Please help!
