ps -ax is showing me this weird process running on a Debian server:
2498 ? S 0:00 error -n retry -t unix -u -c
This appears several times.
Kernel version is 18.104.22.168-xen. Debian Lenny.
Any clue on what this process is?
Thanks in advanced!
It's part of the Postfix MTA as @akramer replied to you.
But, as a tip for your future :) if you ever again wonder if some process is part of another program, use
