This is most likely other applications or processes that are running through the process you are seeing. Try running pstree to see all subprocesses under the process you’re seeing with top.

I am also facing the same problem as below is the output of pstree of my server. Please help to resolve this issue. I have tried to increase my CPU resources but still that process is eating up all CPU resources.
