Hi Johan, Yeah, I'm not doing anything unusual like creating a DB connection per server.
If I run from the CLI: sudo lsof | grep httpd | wc -l The count kind of bounces up and down between 500 - 1,500 If I just look at the contents instead of the count I see a bunch of redundant connections to access_log and the various modules (see below) To be honest I'm out of my element here, so I'm not sure if this is unusual or not. I've updated the apache's launch daemon plist to increase the number of connections apache is allowed to 2048 and I've gone a couple of days without a failure. But I did do an intentional restart last night. Prior to altering the plist I was seeing apache going into the unresponsive state about every 24 hours. When I called Apple they told me to run netstat -m and look at this section: 0 requests for memory denied 0 requests for memory delayed If that goes over 0 you can increase the memory buffer per this article: http://support.apple.com/kb/HT3512 But I've yet to see that number go over zero. (this prints out several times) httpd 6511 _www txt REG 14,2 1996352 17733353 /usr/sbin/httpd httpd 6511 _www txt REG 14,2 393792 17733502 /usr/lib/libaprutil-1.0.2.7.dylib httpd 6511 _www txt REG
