Compile this and see:
#include <stdio.h>
main()
{
printf("Sizeof pointer = %d\n", sizeof(*int));
}
It should say 8 bytes for a 64 bit platform and 4 bytes for a 32 bit platform.

Heh. I've got access to a solaris machine with >4 gig of RAM I could
try running Squid on. This'll tell me whether there's any reason Squid
can't grow its cache_mem usage past four gigabytes.
Did you have any luck with higher value of cache_mem ?
On further testing it seems like the process fails when it hits ~1GB
limit (in top). I read in the FAQ that the msgs could be due lack of
swap space or per process data seg size limit.
I have checked both using and neither seems to be the case.
The other thing that the FAQ mentioned was that there is limit set by
the kernel also. I am not sure how to change that. Does anyone know
how to do that ?
Part of my ulimit output
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
pending signals (-i) 131072
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 32768
pipe size (512 bytes, -p) 8
It is set to unlimited and my swap space is about 750MB free.
line from top command.
Swap: 1959888k total, 1200580k used, 759308k free, 6514844k cached
