increasing nofiles (descriptors) - Jun. 29, '05, 9:04:50 AM

We are getting an error; "too many files open files"

The limits are:

dca-pro236:/usr/dtha/logs$ ulimit -a
time(cpu-seconds) unlimited
file(blocks) unlimited
coredump(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) unlimited
nofiles(descriptors) 1024
vmemory(kbytes) unlimited

I've tried using � ulimit �n unlimited � but it doesn't change the nofiles value. Is there a way to increase the nofiles limit?

Thanks

Which application are you getting this message from ?
Find the root cause of so many descriptors in use might be the real fix.

Try doing it with an actual value instead of the word unlimited.

Hi Rodney

I tried " ulimit -n 2048" and I get

/bin/ksh: ulimit: bad limit: Operation not permitted.

Thanks

To increase the hard limit you have to be a privileged user.
In this instance, you have to be the account Administrator (uid=197108)

There is a registry key (MaxOpenFiles) you can set to increase this limit globally
for all Interix processes. I believe the absolute maximum value is 2048.

The maximum is 4096 by the testing of it.

Hi,
I have not edited any winxp registry before.

I try to add new key MaxOpenFiles using regedit.
I go to HKEY_LOCAL_MACHINE/Softway System/Interix/3.5
then right click and choose
new/key
type: "MaxOpenFiles"
enter
in the right panel, it creates "Name" (Default), "Type" (REG_SZ), "Data" (value not set).
Then right click "Type" and choose New/REG_DWORD
under the Name, it shows New Value #1, I enter 4096.
Reboot the system, check ulimit, nothing changes, it still shows 1024.

Please show me what I did wrong.
Your input is higly appreciated.

You set the wrong registry location.
It used to be under Softway Systems until Microsoft bought it out about 6-7 years ago.
You want "HKLM\SOFTWARE\Microsoft\Services for UNIX\MaxOpenFiles" for Interix/SFU version 3.5.
