I specifically limit connections to (ftpd) all along, which means that for some weird reason, the kernel panic'ed in (ftpd) while it shouldn't have been running at all. 2) the machine is based on a server motherboard and case, manufactured by Intel, and its hardware is highly appreciated. I had no problem with it at all ever. 3) Apache is failing to start on few occasions with sudden 'Signal 4' or 'Signal 11' exit codes. Restarting it would work most of the times. 4) kernel is built using "-O2 -pipe" make options. The above information is the currently used ones. I am building a new kernel now without the "-O2 -pipe" options, using a newly built world. I might add that the server has been rebooting yesterday every 1-2 hours, systematically. Last night I went to the ISP, opened the server up, validated that everything is working, then disabled (ftpd) at all from inetd. Now there's no way to start (ftpd)... Guess what? The server has been up for 7 hours now, and while it did so, it did all the dirty work that it usually does at night: calculating statistics, rsync'ing sources with other servers, building a new world, and other stuff... It didn't reboot, yet. Just few more information while trying to solve this case... /Noor | -----Original Message----- | From: James Long [mailto:stable@museum.rain.com] | Sent: Thursday, June 05, 2003 12:46 AM | To: Noor Dawod | Cc: freebsd-stable@freebsd.org | Subject: Re: Sudden and unexplained reboots | | | On Thu, Jun 05, 2003 at 06:37:55AM +0200, Noor Dawod wrote: | > | > The panic's details are as follows: | > | > Fatal trap 12 = page fault while in kernel mode | | I'd test memory thoroughly next. | |
