Typically, the box just dies. Sometimes it reboots, sometimes it needs a reset. The only thing I've seen so far is this: Apr 28 19:39:01 stats /kernel: issignal Apr 28 19:39:01 stats /kernel: issignal Apr 28 19:39:29 stats last message repeated 12 times Apr 28 19:39:29 stats last message repeated 12 times Apr 28 19:40:35 stats last message repeated 9 times Apr 28 19:40:35 stats last message repeated 9 times I've not found anything useful about issignal - is this something sinister or a red herring? Here's the current top: ast pid: 1048; load averages: 1.37, 1.40, 1.17 up 0+00:41:12 19:42:02 65 processes: 2 running, 63 sleeping CPU states: % user, % nice, % system, % interrupt, % idle Mem: 170M Active, 42M Inact, 130M Wired, 1992K Cache, 112M Buf, 660M Free Swap: 2033M Total, 2033M Free PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 523 www 58 0 7016K 5716K RUN 15:15 80.08% 80.08% httpd 956 www 2 0 8504K 7300K sbwait 0:03 1.86% 1.86% httpd Is there a way I can see what the httpd process is doing? I tried "truss -o /tmp/truss.output -p 523" but there's nothing being logged. This is a busy webserver, so trying to match up hits against processes is a pain and lsof reveals nothing helpful. I think the problem might be some dodgy PHP/MySQL coding, but I've had no joy so far. TIA, Jonathan
