What you described is not squid crashing, but init.
It sounds like you've adjusted the kernel parameters inappropriately,
and that's what you need to fix. I don't know the solution off-hand,
but check the mailing list archives for extensive discussion on how to
tune kernel parameters for large-memory configurations.
Be aware that what you're trying to do may be impossible - i.e. if you
really need 3GB of RAM for squid, it sounds like it's being heavily
used, and may therefore also require a lot of kernel memory to manage
the network resources.q If you need more than 1GB of kernel memory,
you're out of luck with only 4GB total.
