You reached max number of processes per user.

kernel tunable is "nproc".
Are you root?

Daniel,
you have too many processes on the system or under your userid.
ulimit -a should show the limits.
Reduce the number of processes and/or increase available resource and you should be ok.

Thank's!

Dan iel,
ulimit -m unlimited
will reset your memory allowance, to the authorised limit.
However, chances are you have too many processes running.
Issue:
ps | wc -l Gives you the count of your processes.

'kill ' unwanted jobs, which will free up resources.

kmtune -lq nproc # to get nproc
ps -ef | wc -l # to count running processes

or

Check that you ACTUALLY capped max processes:
#sar -v 1 1

HP-UX hostname B.11.11 U 9000/800 04/03/06

18:22:39 text-sz ov proc-sz ov inod-sz ov file-sz ov
18:22:40 N/A N/A 145/1280 0 988/8192 0 1316/8202 0

In this example I have 145 out of 1280 possible running processes.

To change parameter start SAM, change the value (if you change maxusers you also change nproc and some other "useful" parameters on 11.11).

SAM -> Kernel Configuration -> Configurable Parameters
select nproc (or maxusers) with space bar, then Actions -> Modify Configurable Parameter, change it then again actions -> process new kernel and reboot!

regards.
