Why table is full?

[Massimo Bianchi]

Hi,
you are hitting a kernel parameter limit.

check with "sar -v 3 10".


You should check kernel parameter nfile, that is the maximum number of concurrent open file, systemwide.

You can use sam to change the value. IT requires a kernel rebuild and a reboot.


HTH,
Massimo

[twang]

It is because the "nfile" kernel parameter table size limit has been
reached. You have to increase this kernel parameter "nfile".

[twang]

In addition, by default nfile is calculated :
(16*(NPROC+16+MAXUSERS)/10+32+2*(NPTY+NSTRPTY+NSTRTEL))

Therefore you can increase the maxusers parameter. This will solve your problem.

[Rainer von Bongartz]

Increase your kernel parameter nfile
nfile limits the number of open files.

Regards
Rainer

How to increase this kernel parameter "nfile" ?

[twang]

SAM---->Kerrnel Paramters --->Configurable Parameters and change what you want to change.

[twang]

Apply the above changes of parameters, you need to rebuild the kernel and reboot the system.
One more information for reference, once you fail to rebuild the kernel, you need to reboot from the previous kernel, you need to interrupt the autoboot and boot to ISL;
ISL>hpux /stand/vmunix.old

Good luck!
