What script is running by Perl?

Dear fellow unixoids!

I need a little help (just a link would be fine) how can I investigate what specific perl script is eating 100% of cpu of my ubuntu server:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

Couldn't find an answer on Google...
Thanks!

Try

ps -fp 17970

( this assumes that your 'perl' process that hogs the CPU is 17970 as given in your example). You should then find out the guilty script.

Thank you very much!
