We are using memcache in a couple different ways, using the php client with mod_php. Once and a while it seems that something gets hinky in apache/mod_php/memcache client using persistent connections, and calls to $memcache->getServerStatus() will return false, which in our code causes an exception.
I have a few questions: -Is there a way to configure the number of persistent connections to maintain? -Any other settings related to persistent connections? We have a small farm of 3-4 webservers currently going against a single memcached, and when I look for a connection count using lsof or netstat I get a number in the 255ish range -- is this a coincidence, or indicative of some built-in setting? I know there are a lot of variables here, our basic config: Centos5 httpd-2.0.52-41, running worker mod PHP 5.2.6 For now, I've disabled persistent connections, but I'm curious if this is going to significantly limit our scalability as time goes on. Recommendations or advice of others using memcache and php is appreciated.
