Tru64 Unix V5.1-4 i.e. on patch kit 6.
In the past couple of days the server has started reporting the following in the messages file:-
Apr 28 15:29:57 lysithea last message repeated 2 times
Apr 28 15:30:00 lysithea vmunix: task_create() failed for pid 425887: max_proc_per_user (=4096) exceeded for uid 202.

I am informed by our DBA the problem appears to be caused by a Oracle Enterprise agent which keeps on bouncing the databases.
Yesterday the DBA stopped and restarted the Oracle Enterprise agent but only fixes the problem for a while until it starts to reporting these max_proc_user exceeded messages again.
Has anyone got a fix for this type of problem?
Solved! Go to Solution.

Re: max_proc_per_user exceeded for uid
is this a new build of old server and you suddenly started to face the issue.
You may have to contact DBA team as to how many process oracle is expected to run.
Well this parameter sets the maximum number of proxess a user can run.
CHeck if some defunct process is there.

Re: max_proc_per_user exceeded for uid
I'll speak to our DBA to check how many processes oracle is expected to run
I cannot see any defunct procesess.
Yesterday the DBA restarted the Oracle Enterprise agent and so far further errors have been reported.
Thanks

Has nothing changed in the last 5 years ? I'll take a guess that the Oracle Enterprise agent might be a relatively recent addition...
Which user relates to UID 202 ? (# grep 202 /etc/passwd) That may give you some hints as to what is happening.
It might also be useful to let us know the versions of Oracle that you're running....
Cheers,
Rob

Re: max_proc_per_user exceeded for uid
this goes even worse when temp-files are used and no effort is made to make the filename unique, such a script bites it's own tail....
first inspect the cause the first instance is taking longer than normally.
(tables grown ore locked, inspected file larger than in the past?)

Re: max_proc_per_user exceeded for uid
Over the last 5 years we have successfully applied patch kit updates and updated the Oracle database on it. The current Oracle database is version 10.2.0.3.0.
Yes the DBA recently in Feb 2009 installed Oracle Enterprise agent and it has been running fine up until 27th April 2009 when these errors started to be reported.
OEM version is 10.2.0.2.0.
Two weeks ago I applied a ERP patch kit fix for a known panic problem.
Grep of UID 202 displays this:-
# grep -i 202 /etc/passwd
oracle:*:202:200:Oracle Account:/dba/users/oracle:/bin/ksh
Rob, can you advise me now for a fix?

Re: max_proc_per_user exceeded for uid
I have advise the DBA to log a fault call wiith Oracle to shed some light on this problem.
Thank you.
