Summary:                    squid 3.4.4 crashes on Solaris 10
Description: 
I have been using Squid 3.1 for quite awhile with no problem. I recently
upgraded all my CSW packages and Squid 3.4.4 came with it, no option
otherwise it's in stable/unstable/testing.
The problem is that it is NOT stable: it exits after awhile.
It's running as a service (cswsquid) as per the package.
This on a T2000 Solaris 10 148888-05 with 8GB RAM and about 600GB of
available disk space .
I had made no change to the configuration between 3.1 and 3.4. I
subsequently have tried both aufs and my original ufs (diskd isn't
available) to no avail.
I increased the size of the disk and memory cache to no avail.
Squid will run happily as long as users are only tunneling through it; once
some caching gets going with regular http it exits.

I'm not finding any core dumps in /var/opt/csw/squid/cache or the 00
directory under that.
I can provide squid config files and log files.

I pushed 3.4.5 in the meantime which still crashes from time to time. What
is interesting is that the crashes vanish completely when squidguard is not
used (that means no URL filtering is used at all).
