I'm experiencing an odd problem with a 2.2.2 machine that has served faithfully for well over a year. The program running on that machine is extremely memory intensive and often runs as high as 200M and higher. Because this memory gets fragmented, we reboot the machine often, usually every 2 to 3 days. The program itself is in the process of being rewritten to avoid some of these issues. Up until the last 3 weeks or so this pattern has served us well. Recently, a fairly consistent pattern has been developing where after a manual reboot the machine will panic between an hour and two hours later with the message: /kernel: panic: get_pv_entry: cannot get a pv_entry_t After it panics and reboots itself the system is happy for the next 2 or 3 days. I've read the comments in /usr/src/sys/i386/i386/pmap.c so I'm relatively familiar with the meaning of the error message itself. What I don't understand is why it's rebooting itself regularly after a manual reboot, and why (running the same startup scripts, processes, etc.) it's "happy" after a panic instead of being happy after a manual reboot. I realize this is all very odd, however any pointers or assistance would be welcome. Doug PS, searching the archives was useless since a search for pv_entry_t returned a large number of entries, none of which had that item in it. I think the problem is related to underscores in the search item. -- *** Chief Operations Officer, DALnet IRC network *** *** Proud operator, designer and maintainer of the world's largest *** Internet Relay Chat server. 5,328 clients and still growing. *** Try spider.dal.net on ports 6662-4 (Powered by FreeBSD) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
