Re: [squid-users] your cache is Running out of filedescriptors

[Jeff Donovan]

ok let me get this straight

send a hup signal to squid
and restart with
./squid ulimit -HSn 2048
(doesn't look right to me)

./squid -h
doesn't show much in line with what you are saying. Do i need to 
recompile squid maybe?

It seems that you OS have support up to 12288 file

but you have not started squid with more than 1024
file des.. so you will have to kill the squid process
and then you will restart it with command like that.
ulimit -HSn 2048 or more than that.

and than start squid

How do I check my maximum filedescriptors?
Do sysctl -a and look for the value of
kern.maxfilesperproc .
How do I increase them?
sysctl -w kern.maxfiles=XXXX
         sysctl -w kern.maxfilesperproc=XXXX
Warning : You probably want maxfiles >
maxfilesperproc if you're going
to be pushing the limit.
What is the upper limit?
I don't think there is a formal upper limit inside
the kernel. All the
data structures are dynamically allocated.  In
practice there might be
unintended metaphenomena (kernel spending too much
time searching
tables, for example).
####Here is my kernel output: i would assume i could
increase the
maxproc and the maxfiles.


[squidx:~] root# sysctl -a | more

WARNING! Your cache is running out of

 Unless someone would launch some kind of denial
of service
 attack against your squid. The 2 lines are
normally unrelated
 to the out of file desc. problem.
 Check access.log to see which kind of requests
are being processed
 by squid during the time of these error(s).

 However you may need to increase the available no
of file descriptors.
 I do not know how to do this on OSX however.
