Hi All,
I'm having a very strange problem and am hoping someone on here can
help. I'm running a typical Apache(1.3.6), mod_perl(1.21), Mason(0.81),
mySQL set-up on 4 big RAM machines (database is on other machines). I
start up the servers and after a few minutes the state of the processes
ends up as "semwai" and the apache processes just stop taking requests.
Here's a quick glance at some output from top:
50201 www -4 0 15544K 10352K semwai 0:00 0.00% 0.00% apache
50249 www -4 0 15432K 10280K semwai 0:00 0.00% 0.00% apache
50227 www -4 0 15428K 9808K semwai 0:00 0.00% 0.00% apache
Tried many different combinations of MaxClients, MaxRequestsPerChild,
along with KeepAlive On/Off, nothing seems to help. Currently I'm at 48
servers on each of 4 machines, mySQL is set-up to take over 800
connections (so the 100 limit has already been modified.) Not swapping,
not heavily loaded.. Roughly only 30 connections to any specific
machine at one time.
Has anyone seen this or better yet what's the cause or some suggested
things to look at or fix?
Thanks
