"Proc table is full" dmesg error :URGENT

[vselvaraj]

Dear All
Some 3 days back I raised one problem in this
forum. ie) In a mail server m/c Sendmail 8.8.6 L-1000, HPUX 11.00, very frequently "file table is full" error message was comming while executing dmesg
command.that timr sendmail will stop.
I got solution that to increase nfile kernel parameter to 12000.

I had done the same ie from 910 to 12000.
Today morning it is giving "proc table is full" message, & Sendmail stopped working.
Please help me to correct this issue.
Application is down now.

advance thanks
V.Selvaraj

The most likely cause of the error "process table is full" is that
the operating system parameters maxuprc and/or nproc are set too low.

Maxuprc is the maximum number of processes that any one user can
have simultaneously. The superuser is exempt from this limitation, so
if the superuser gets this error as well, then nproc is probably too low.
Nproc is the maximum number of processes on the system at one time.

Another possible cause of this problem is having "ghost" child
processes on the system that do not terminate when the parent processes
terminate. If shutting down the system does not clear the problem,
then this is not the cause.

vmunix: proc: table is full

This message relates to the kernel parameter nproc. You should increase nproc

# sar -v 5 5

Look at the 'proc-sz' column, this will show the max and where it is now. Once it reaches the max you'll notice the error. Also check you're syslog to make sure it's not an old message.

Dear
If I need to increase 'nproc' and 'maxuprx'
how much I have to ?

If there is any relative increase to be required/ because I increased 'nfile' from 910 to 12000

My advice is for a sendmail server set nproc to 1000 and maxuprc to 500

Hi,
Keep the values as follows:
NPROC=4700
NFILE=12000 or (What I have 9850)
NINODE=3931(Keep below 4000)
NFLOCK=5900
They are dependent on NPTY and MAXUSERS(macro)
