Hi,
I've got this strange behavior in a production site that until a recent
upgrade never showed this kind of thing:
I've set maxclients to 50, maxrequestsperchild 1.
What happens is that the server runs fine, is fast, etc, but the number
of apache processes climbs gradually until it reaches ~maxclients, then
will no longer serve pages.
I thought this was due to children not exiting, but some of them
apparently do, as the number of processes rises and falls on its way to
the top.
What is Apache supposed to do when you set maxrequestsperchild to 1?
I'd have thought each process would exit immediatley after serving
something.
I'm inclined to think there's something in my code that's hanging, but I
read that the symptom of that is processes consuming large amounts of
CPU - they're not, and memory usage is normal, too (~10M).
Another symptom: sometimes when the processes are nearing the top,
they'll start haging, but one by one; if I hit stop on a non-responsive
request, then re-try, it serves fine.
I'm using the debian package of modperl 1.21 statically linked with
apache 1.3.9, and HTML::Embperl 1.2.1 ( I think).
Any insight greatly appreciated.
Tom
