I think that raising UPAGES did reduce the frequency :of the crashes, although I'm not sure if it was sufficient for squid's :humungous stack usage, or does that even matter? : :-mohan Squid's user-stack useage is unrelated to the UPAGES (kernel stack) issue. Interrupt stacking in the kernel is the issue. I don't know if your problems are related to the kernel stack but it's worth raising UPAGES to 4 to find out. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
