Ok, 2.0.27 kernel, with mildly expanded limits, the following kernel Ooops:

This machine is running squid and only squid. This particular crash looks seriously wrong to me.... any ideas? Follows are the resource limit 'tweaks' I've made:
include/linux/net_alias.h - line 28, NET_ALIAS_MAX_SLOT = 512, not 256 include/linux/fs.h - line 30, NR_OPEN = 1024 include/linux/fs.h - line 39, NR_INODE = 8192 include/linux/fs.h - line 40, NR_FILE = 4096 include/linux/limits.h - line 4, NR_OPEN = 1024 include/linux/limits.h - line 9, OPEN_MAX = 512
