Hi,
I've been working on a machine which is crashing as random intervals
with no apparent faults being logged.
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:

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
