Check the usage of 'nfile' ,'maxfiles' and 'maxfiles_lim' kernal parameter.

what is the OS HPUX version ?

do post sar -v 5 5 output as well

Do check the system table in glance for the
proc & file consumptions.

we're on HP-UX 11.23

maxfiles is static, current value 2048
next boot value -
default value 2048
usage -

maxfiles_lim is dynamic, current value 4096
next boot value 4096
default value 4096
usage 50%

kcusage -d maxfiles_lim returns:
Usage %
2048 50.00

kcusage -d maxfiles returns:
Unsupported Tunable: maxfiles

If it has more than 2048 open files now, you may want to stop/start this process.

>Usage %: 2048 50.00

Hmm, if only 50%, why too many files open?

Can we see 'kcusage -d nfile"

I had to reboot my servers last weekend for something else.

I do not see the message anymore.

Thanks for all the help for this.

Thats good !!
I would still appreciate if you may monitor the
usage of "maxfiles ,maxfiles_lim & nfile" with
kcusage -d.

Thanks

Hi,

You can monitor with kcusage as mentioned or configure an alarm with kcalarm or to the root mail, so that you know the tunable is exceeding the threshold.
