Well - alot of people thought it was because of .cshrc (which isn't in use)
or tcsh creating a loop. I looked at the outputs that I captured, and when I
initially killed some of the processes, new ones started - filling up the
number of processes allowed for that user. I double checked all the
processes that were running at the time, and there wasn't anything else
running from that user, or any other user, that would have spawned them.
I'll keep an eye on that machine and see if it occurs again.
Thanks everyone for the info you've sent.
Michael

Hi,
More on this - I found out from the 2 users that they were using vi and more
on a couple of text files when this occured.
The users have sinced relogged into the machine and did the same stuff (vi
and moreing files) but the problem hasn't occurred again. Maybe it was just
a freak thing who knows. Odd tho.

Hi,
About 30 minutes ago, a user account on our test server had to
disconnect
because they couldn't do anything (i mean anything, nada, nothing). The
error they got is:
task_create() failed for pid 16737: maxuprc (=552) exceeded for uid 640.
task_create() failed for pid 16737: maxuprc (=552) exceeded for uid 640.
task_create() failed for pid 16737: maxuprc (=552) exceeded for uid 640.
task_create() failed for pid 16737: maxuprc (=552) exceeded for uid 640.
.profile[4]: cannot fork: too many processes
When I did a ps -ef for this user, it showed 552 processes running, all
itentical to this: (except PID numbers were different):

What would cause this?? I have never seen this happen before. I've sent
a
message of to the users who use this account and asked them exactly what
they were doing around this time.
If anyone has an idea..
Thanks - Mike
