Hi folk,
I want to start this message by saying, what I'm about to describe is
completely vague and I don't expect to get a solution response. ;)
Basically, I'm out of ideas and am looking for some suggestions as to how
to debug the issue I'm running into.
Starting about half a year ago, slapd started "just dieing" out of the
blue. Not a think in the logs shows up to indicate what might have caused
it. The last query that I see in the logs before a crash always seems to
be nothing special. I don't even see a core dump being generated yet, but
then that may just be because I don't have the proper setup to get a core
dump at this time. We were running the last 2.2 and upgraded to the
latest release of 2.3 to make sure it wasn't an "old version" issue.
Unfortunately, slapd still dies a fair amount on us. It appears to be
fairly unpredictable. I've seen it crash within 1 minute of starting up
slapd (then a subsequent startup 'takes' just fine). I've seen it crash
when there were a number of network issues going on. I've seen it crash
out of the blue when nothing appeared to be going on. I don't really have
the drive space to turn on max debug logging 24/7 until the problem
occurs.
We're thinking about setting up something to watch all of the network
traffic going to one of the boxes until it dies. (assuming we can find
something with the resources to do that)
That all said... since I have nothing solid to present, do you all have
any suggestions of what would be the best way to track down what's going
on? I'm literally out of ideas unless my berkeley db config is somehow
causing the problem or something like that.
I apologize for the vagueness. =/ Any ideas/suggestions?
