Why do you think it has anything to do with httpd? This is firmly a "When I do things with PHP, PHP doesn't work .... therefore httpd has a problem" type diagnosis.
I'm sorry that I pointed my finger at httpd. It could be anything in the chain (HW - kernel - httpd - php ...).
I just asked here because I though people would have ideas how can I debug this further. I'm sorry if I upset anyone with my post. That was not my intention.
The first thing I would suggest is asking on a PHP list why using a memcached session backend stops working with large numbers of clients.
There isn't a large number of clients, it's only a large number of vhosts - which translates in large number of FDs in use.
The second thing I would suggest is not running mod_php (I am assuming; you don't mention, but you are stracing httpd to see PHP's select()s...) but run php-fpm, which separates out PHP from httpd. It also performs a lot better.
I will take a look into it, thanx. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
