I had a similar problem running squid on BSDI initially. You're
right - basically, your problem is that you are running out of RAM or
haven't allocated sufficient RAM resources to your squid process.

In BSDI 2.1, I defined the following in the kernel config file:

        options "KMEMSIZE=\(16*1024*1024\)"
        options "DFLDSIZ=\(64*1024*1024\)"
        options "DFLSSIZ=\(4*1024*1024\)"
        options "MAXDSIZ=\(96*1024*1024\)"

..and then recompiled the kernel. This was for a box which is a dedicated
proxy server with 128Mb RAM.

Before I start squid, I run

        unlimit datasize
        limit maxproc 2048
        limit openfiles 4096

in the same script that starts squid.

My guess in your case is that although you may have unlimited the datasize,
your max datasize may still be too small. Try recompiling the kernel
with a greater max datasze (not sure how you'd do this with linux
offhand), or reduce the cache_mem size in squid.conf.
