max_proc_per_user (=2048) exceeded for uid

Hi,

I get these errors:

19:13:12 vmunix: task_create() failed for pid 1098747: max_proc_per_user (=2048) exceeded for uid 974.
Jul 5 09:46:41 vmunix: task_create() failed for pid 1476629: max_proc_per_user (=2048) exceeded for uid 974.
Jul 5 09:46:45 vmunix: task_create() failed for pid 1476629: max_proc_per_user (=2048) exceeded for uid 974

When the problem is happening I check the user procs(with ps -ef) and there are only 180 listed.

how is this posible?, could it be forking 2000 process and killing them in millisenconds ? that i can't catch them with ps?

how can I track down the process that is generating this problem ?

thnx
Windows?, no thanks

It could be a simple fork bomb, where a script is calling itself by mistake.
After the error, the processes quickly terminate.

Have you asked uid 974 what was going on at that time? (If it is a mistake, usually they don't continue.)

are u getting these messages again, if not it might just happened becaouse of smthing which you may or may not find.
You will have to carefully check what was running that time.
Possibaly a cron script does it sometimes.

If its not happenieng again, you can ignore this.

It's tibco the user which is reaching the limit. They say they aren't doing anything different.

It has happened several times, but I can't catch what is generating this forking.

Do you see any specific time when this is happening.

I don think there is a specific way to check untill and unless you logged in or u see any pattern which could put you near to what is happening.

we are looking into the user shell scripts, to try and find out, if they are the cause
