Perl Processess On A Cpanel Server

Its a cpanel server with latest version.

I have been noticing that several perl process are running most of the times which takes a lot CPU resource percentage, The server wads deployed som 5 months back but i have been noticing these perl processess from like 10-15 days, it looks like this

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
31097 nobody 25 0 7188 3284 1176 R 46 0.2 1322:57 perl
25122 nobody 25 0 8988 4104 1160 R 45 0.2 620:22.34 perl
28144 nobody 25 0 7852 3712 1232 R 34 0.2 600:18.11 perl
6878 nobody 25 0 9316 4064 1104 R 33 0.2 1007:38 perl
25120 nobody 25 0 8980 4068 1128 R 33 0.2 623:28.04 perl
8263 nobody 15 0 8496 4308 1260 S 2 0.2 0:28.21 perl

What should i do to close them all and to make them occur not anymore, I dont think there is any perl based script working on the server. Not even much PHP based functionalit, Only static HTML pages.
