SSL handshaking very slow

November 25, 2010 06:39AM
hi there,
I'm running the latest stable version of nginx and running into a strange issue. after a few hour of operation, SSL handshaking stars to become very, very slow. in some cases, establishing an SSL connection will take over 30 seconds and the browser consequently timeouts. that said, when an SSL connection is established, everything is blazing fast. similarly, accessing the site over HTTP is fast.

restarting nginx doesn't seem to fix the machine once it gets into this state. the only fix is to restart the whole machine. I generally have something like 20k SSL sessions active on this machine. changing the SSL session timeouts, etc. has no effect once the machine gets into this state. are there any obvious parameters (either nginx specific or system) that I should be looking at? thanks greatly in advance.
