Our web server has crashed three times in as many days, and I'm having some trouble tracking down the cause. The machine is a Pentium 233 running RedHat 5 with most of the errata applied, and a 2.0.33 kernel patched to allow 1024 open fd's per process (so apache can keep logfiles open for all our virtual hosts). The problem didn't start until after I installed the new kernel, but it was four days later, so I'm not certain this is the cause. The machine hung for about 20 minutes Saturday night, then rebooted itself. Sunday night, it completely locked up and had to be hard-reset. Neither of these instances left anything conspicuous in the logs, since (presumably) syslogging was fubar'ed along with the rest of the system. So now I need to know what caused this and how to prevent it, but I really don't have many clues to go on. (Does anyone have any general advice on how to determine what's going on in an unattended crash like this?) Today when it crashed, it did leave the following in the log: Apr 20 16:00:04 multivac kernel: Unable to load interpreter ...and this was the last message before the reboot. Also, our webmaster logged in just before the crash, and sent me some of his session output: [root@multivac bonafede]# w 3:59pm up 12:19, 3 users, load average: 8.52, 4.81, 1.95 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT dwayne ttyp0 hal.cy-net.net 4:05am 3:35m 0.17s 0.04s bash dwayne ttyp1 hal.cy-net.net 9:07am 5:29 0.59s 0.42s bash bonafede ttyp2 shark.cy-net.net 3:58pm 4.00s 0.49s 0.07s w [root@multivac bonafede]# top Segmentation fault ...so whatever's causing it _is_ causing a load spike, but since it also caused top to segfault we don't know what was hogging resources then. So, any ideas? ____________________________________________________________________________ I.
