Re: Squid-2.4 memory leaks

Which by 100% confirms that you are seeing a servere problem of memory
fragmentation.

Why 100% certain: The free memory is "constantly" growing, not
displaying any signs of a rough sawtooth pattern. But then there is some
alarming sharp edges there where the amount of free memory suddenly
grows so there may be more to it after all.

I'd recommend start looking for another malloc() implementation. You say
you have tried dlmalloc but to no avail.. odd. historically dlmalloc has
been able to cope with Squid loads quite well on other platforms where
the systems malloc() does not.
