Re: [squid-users] Very strange squid problem

hello

squid version is:
squid 2.6.5-6etch1

I dont have any of the features you related. Disk cache is:
cache_dir aufs /var/spool/squid 5000 16 256

i have debug_options ALL,9 and no errors reported on cache.log...

We have just moved the server to new hardware, and the problem still goes
on.
