Re: [squid-users] Bad Amount of File Descriptors

Hi squid team,

Well, finally, I'm still facing some troubles with my amount of FileDescriptors.

I've put the Ulimit and Sysctl tricks, but SQUID is still handeling 1024 FD.
At least this is what my SQUID's Startup script said.

I'm putting squid in an ISP environnement, and I've set FD Limit to 256 000, may I increase the amount of IO to 2 000 000 or upper??

Shouldn't I saw the SQUID default number of FD be replace by my settings on the SQUID's startup script instead of the usual 1024?

Many thanks in advance.

Hi Amos

First of all, thanks for your support.

Secondly, That a good news about the re-compilation not needed anymore ;)

Finally, I have had the following instruction on my SQUID init's script:

ulimit -HS 256000

but unfortunatly, I still not able to see a value bigger than 1024 on the SQUID starting logs, is that normal?

I think it because I don't have any warning regarding the FD on my logs.

Many thanks.

3.1 supports the max_fd config option, no need to recompile anymore :).

There is some bug as yet untraced breaking the max_filedescriptors
squid.conf option from working without ulimit.

For now you still need to change squid.conf and run ulimit before
start/restart/reconfigure to raise the number Squid sees available from
the OS.
