Issue Process with user syslog and command cache-main is constantly at 100% CPU

That process looks suspicious to me. You should investigate it to find out where the binary lives and which process was calling it.
List open files/descriptors/sockets of the process: lsof -p 9977
Retrieve parent process ID: ps -o ppid= -p 9977
Then do lsof -p with the parent process ID
Also, do a full "ps auxwww" to list all of your processes.

Ah OK, so "cache-main" belongs to Varnish, so nothing suspicious.
I can't tell you why that varnish process has such a high CPU usage, you will have to debug that using varnishtop and other tools, but this is outside of the scope of Plesk. Also, check your varnish logs if you see anything that will give you an indication about what's going on.
