Hello,
please increase the kernel parameters
maxuprc-- maximum no. of processes for a user.
nproc ---Maximum no. of processes.

rebuild the kernel.

Thanks

This could be either of the kernel parameters maxuprc or nproc. Mostly nproc.

Increase them.

#/usr/lbin/sysadm/system_prep -s /stand/system
#vi /stand/system (make changes)
#mk_kernel -o /stand/vmunix
#shutdown -r now

Ricky,

Seems that the system has hit the limit
of maximum number of processes it is allowed
to run. To increase it, change the
kernel parameters NPROC and MAXUPRC.
NPROC specifies the maximum number of processes
which can run on the box.
MAXUPRC specifies the maximum number of process
which a user can run.

You can use SAM or command line to do this
change. The system would need to be rebooted.
