Perl using 95% of CPU

Recently my server has been crashing every hour, and I still can't find the problem. It overloads and reboot all the time, but usually when I run "top" it won't show anything overloading. Except for now, here's what I got on top of the list:

Code: 
  PID USERNAME PRI NICE   SIZE    RES STATE  C   TIME   WCPU    CPU COMMAND
 2902 vipclick 139   20   223M   220M CPU1   1   6:33 96.73% 96.73% perl5.8.7
This happened showing as several users, including root. What could it be?
