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
