Thank you Les, so init does the forking for me?
I'll try it in few hours, when I have less users online.
And I wonder how often does init try to run
a program, before it stops for 5 minutes...
Mark, my pref.pl is 80 lines long, the rest is in few modules.
Yes, perl interpreter 5.8.8 crashes for me once a week,
but I don't really have a chance to solve it - I'm not a
perl interpreter developer myself, I don't have an easy
test case for them to try, I don't have a 2nd server or time
to reproduce it myself. I need to solve this problem now
(going to vacation on Sunday).
