Any userland program that is able to produce a kernel panic mean there
is a kernel bug - no ifs no buts - userland must not be able to crash
the kernel no matter what.
FWIW squid uses a lot of memory, not only does it cache "hot" objects
in memory but has a lot of memory tied up in managing where objects
are on disk. Given that squid is trying to accelerate web accesses
using large slabs of memory to increase speed is a not unreasonable
thing to do.
