High CPU usage on linux server by [sync_supers]

Ali EB
Hello, our server has 8 cores and the cpu usage is 0.2 to 4.0 when we lunch it for the first time - restart- but after 24 to 48 hours the process goes up to 10 to 40 sometimes on WHM we found the the current process that takes most cpu are [sync_supers] there are like 7 of them and all of them are by nobody and using over 70% cpu each.

    It's a kernel thread, and not something that's associated with a cPanel feature. A similar question was asked on a third-party website: [url=http://serverfault.com/questions/643892/high-cpu-load-on-centos-with-process-sync-supers]High CPU load on Centos with process sync_supers - Server Fault Thank you.
