FW: why Squid 2 overruns cache size ?

I have similar problems, too.
Our configuration: Squid 2.0p2, Solaris 2.5.1, 4 GB disks.

Cache size keeps growing beyond the limits defined in squid.conf (although
sometimes, disk usage drops off).
We tried with "low" limits (<<100 MB); and we can see Squid using between 120%
 and 200% of the defined limit.
Eventually, the Squid stops with the following message:

FATAL: file_map_allocate: Exceeded filemap limit

I'm seeing a similar problem, not sure if it's related.
Basically, as the cache fills up the disk usage increases, but I see
strange results from a df -k, where the total disk space is reported as
6400megs with 5400meg used, but there are only 200megs available. Squid
eventually reaches the limit and resizes the swap size down a few
hundred megs and things return to normal. Setting the disk size lower I
can see the disk usage (as reported by df) fill up to near 95% and then
drop off significantly, before Squid reaches 90% and starts LRU. The
usage appears to stabilise after the cache has been full for a few days,
then I can increase the cache_dir size.
Any ideas?
