RE: Solaris x86 and Squid

System: Dual P2 300 with 512 MB of RAM
Drivers: Mylex Raid Controller
Malloc: DLMalloc (--enable-dlmalloc)
OS: Solaris 2.6_x86
Compiler: GCC and GNU Make

I've seen this memory leak in every version of squid since we stated using
it about 3 months ago. I've been complaining about it since then too but no
one have every responded. Because of the massive load I am able to put on
my cache servers I see this leak within 4 hours instead of 2 weeks. After
the system runs out of memory the processor tries to compensate and when
that no longer works your pretty much dead. The curious thing is that after
you kill the squid process the memory is not released. This has led me to
believe that the memory leak lies somewhere else. I had considered the
possibility of the disk sub system or the RAID driver. I spend over a week
on the phone with Sun and they could not see anything, or so they say. I'm
currently investigating the possibility of the leak being in IPFilter.

Yes I am aware of this; I'm talking about endless growth (squid with a
32M cache_mem growing to >256M over the course of two weeks). stats in
cachemgr.cgi seem to support this, if I read them correctly.
