High load on server, can't find cause
Hi,
since a couple of days my cpanel server (VPS) has a very high load without reason. No programs are consuming high memory or cpu. Load is constant around 20, and due the high load a number of services are failing
This is the result of top:
I'm trying to discover the cause of the high load. Since I don't see processes consuming high amount of cpu or mem, where can I start looking? Thanks!
