Hi All,
I have had some recent crashes and am trying to diagnose what might be causing the problems. I'd really appreciate any suggestions or ideas on where to look for info.
crash: full on kernel panic. This seems to have been cause by me stopping and restarting sendmail. I use a shell alias which stops, waits and restarts sendmail. See [item 1] at the end of this message
httpd signal 11: I seem to be getting a bunch of these recently. I used to see these with earlier versions of PHP. Has anyone had these with 4.3.10 (side note: 4.3.10 does not seem to report error line numbers correctly).
runaway process: When I checked in this morning mysql was at 80% wcpu and my 1 gig of swap was all used up. my guess from the logs is that an httpd process went down leaving mysql with nowhere to go [see item 2] at the end of this message
question: what does <process-name> mean in top? Shows as IWs or IWs+ in ps
eg: 58939 root 10 0 648K 0K wait 0:00 0.00% 0.00% <sh>
Thanks for your time,
Steve
