Hello,

The problem is, the load is never all that high when it does this. I have
had this box going at 110+ reqs/sec, feeding 550K/sec without a problem, and
it will die at 50 reqs/sec or less. It does not seem to have to do with
load. Only once have I ever had a malloc error in the cache.log or syslog.

I agree that I am pushing the box quite a bit, however I have semi-decent
hardware to do it too. But there does not seem to be a critical point where
squid fails, and it will mostly do it early in the day before it hits high
loads.

Ron
