Hello all,
above issue seems to be old. But I did all according to docs/wiki etc.
Squid is used as accelerator. We currently have 156 GB in use all
spreaded on four disks with 6206547 files which makes an average object
size of ca. 25 kB. But there are a lot of files smaller than 10 kB. The
average outgoing traffic is at 12 Mbits/sec
"ulimit -n 65535" in init.d-script and compiled with 65535 file
descriptors(more infos below).
What happens is that Squid runs for about two days until there are no
more file descriptors left and it just stops serving files with all
processes still running. In cache.log I can find this:
2008/08/04 06:44:01| client_side.cc(2690) WARNING! Your cache is running
out of filedescriptors
Has anyone here an idea where to look or what I can do?
Thanks for any help,
