Re: Squid seems to "HANG UP"!

Hi again Michael!

I tried to make some research on the file descriptor thing .. and i came out
with your site at http://wwwcache.ja.net/FAQ/FAQ-2.html ... and you
mentioned that hopefully linux kernels higher that 2.2.1 should already
include the alan cox's patches. My kernel is 2.2.6 ... does it? Also my
squid's version is 2.2.STABLE4

I checked my src files and found the following:

posix_types.h : __FD_SETSIZE 1024
fs.h : NR_OPEN 1024 (note: could not find INR_OPEN just NR_OPEN)
types.h (under /usr/include/gnu) : __FD_SETSIZE 256

I also checked my files in /proc/sys/fs directory:

file-max : 4096
inode-max : 8192
super-max : 256

Below is a snip from my cache.log .... as observed, squid can detect 1024
file descriptors.

Hope this helps ... so that you or someone may help me.

Finally ... my cache.log seems not log anything during the times when the
server doesn't respond to any request .... the clients just poll (ip of my
proxy appears on the lower-left corner of the browser) until finally issuing
a pop-up error indicating server connection error.

Thanks again for any help that you can extend.
