Don't open so many files?

Close some files?


What, exactly, are you doing when you have
this problem? How many open files do you
have? (How many do you need?)

what does ulimit return?

[Bill McNAMARA_1]

try
ulimit -u unlimited

"parameter file-max"???

what change u made on /etc/security/limits.conf?

[Fadia Almarei]

this is what i chande in limits.conf file

* soft nofile 65535
* hard nofile 65535


ulimit -u gives
137215


ulimit -n gives
65535

In HP-UX nofiles is controlled by kernel parm maxfiles(soft)

#kmtune|grep maxf
maxfiles 2048 - 2048
maxfiles_lim 8192 Y 8192

#ulimit -a|grep nofiles
nofiles(descriptors) 2048

So in LINUX you may have somthing simialar and give a shot by changing fs.file-max. Your "soft nofile" and fs.file-max are possibly related.

# sysctl -a|grep -i fs.file-max
fs.file-max = 8192

After you change parameters in /etc/sysctl.conf, don't forget to run:

sysctl -p
