I'm running 0.4rc1 on a semi production server. Everything is going
well but I just noticed this in the logs:
[Fri Apr 16 14:40:40 2010] [notice] child pid 6889 exit signal
Segmentation fault (11)
At the moment I have only seen the one occurrence so I'm not too
worried, but I don't know where (if any) apache keeps core files?
How would I debug this?
Hello!
Info about apache core dumps here:
http://httpd.apache.org/dev/debugging.html#crashes
If you manage to get some core dumps, you can try sending them to me, so
I can take a better look.
Also, my server is running ~30 vhosts and i'm seeing in excess of 300
apache processes with very little traffic. What options should I
change to keep the overall processes down to a minimum?
How many requests per second are you getting at that time? There may be
multiple reasons for this.
I cannot find any documentation on the ProcessorWaitTimeout parameter,
could someone enlighten me?
ProcessorWaitTimeout is used when the Processor's MaxProcessor limit has
been reached. First argument sets the maximum time (in seconds) the
multiplexer should wait for the processor before it drops the request.
The second argument sets the amount of levels between waiting the
maximum time and not waiting at all (each time the multiplexer is unable
to pass the request, it starts to wait less time for free processors).
If the multiplexer starts to drop requests, it also writes it to the log
and lowers the AVAIL field on the processor group (this can be seen via
server-status).
