Cyberpanel / Centos 7 CPUmemory issue kswapd-

My cyberpanel server is running overtime. Disksize was 100% but I cleared most files and now on 60% but somehow this kswapd0 process is taking 200% CPU constantly. I do not know what to do but need a fix soon.

Please explain to me the problem before accepting this job. It is urgent.
