Re: [squid-users] FileDescriptor Issues

Hi All
I have recompiled squid with 6400 FDS I tried with 65535 and I got a warning
that 65535 is not a multiple of 64 and it may cause some problems on some
systems.
so I changed it to 6400
I completed the installation started Squid now it's showing 6400 although
the system is set to 65535
I have one question, from your experiences with squid, would 6400 FDS be
enough?

Thank you all for your help
Regards
Adam

A problem I found is that you have to set ulimit BEFORE you compile it as
well.

I built everything from scratch and everytime I rebuild it I have to :

ulimit -HSn XXXXXX

(XXXX being whatever you want it to be)

In /etc/init.d/squid (the script I use)

[snip]
PATH=/usr/bin:/sbin:/bin:/usr/sbin
export PATH
ulimit -HSn 32768
[snip]

That way every time I run the script it makes sure that it sets the FDs up
to where they need to be.

I'm guessing that if you have a busy server it is crashing after a little
while of running....... ;-)
