Hi, I'm using Tomcat 6.0.20 fronted by Apache 2.2.10 with mod_proxy_ajp. I'm trying to figure out some tuning/tweaks to our AJP connector, and have run into some oddities I am not sure about and want to see if someone can shed some light on this.
The primary problem I'm trying to solve here is the effect of keepAliveTimeout at the connector level. I'm reading http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html and it tells me that this is "the number of milliseconds this Connector will wait for another AJP request before closing the connection. The default value is to use the value that has been set for the connectionTimeout attribute." Here's the kicker - I can't see where this ends up getting used - the behavior of the connector threads (watching them thru jconsole for instance) doesn't seem to change no matter what I configure this to. Furthermore, tracing thru the code, it looks like this setting is not even used (tho I could be missing something here). The Connector class tries to do a setProperty for keepAliveTimeout on the JkCoyoteHandler class instance, which doesn't have a setter for this, so it goes into a properties map which, if I am following the code right, never gets used (meaning this particular keepAliveTimeout setting never gets pulled out). I tried using tcnative under Windows to see if that made any difference, and indeed it does - setting a value for keepAliveTimeout DOES get set but then once that timeout occurs, my CPU utilization goes to 100% and my system crawls to a halt until I kill the tomcat java process. So... can someone explain whether the connectionTimeout and keepAliveTimeout really do anything (useful) for AJP? What am I missing?
