Re: too many open files

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.

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?

Re: too many open files

Re: too many open files

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.

Re: too many open files

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

Re: too many open files

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.
