If worker == thread, I have 1500 max threads on the tomcat side. When I ran the test straight against the tomcat servers, they only consumed ~160 threads/tomcat instance. When I put apache in front of it, this number goes up to ~1100. The network is a gig ethernet and is only about 15% utilized. I have read about bugs with apache 2.2.x and mod_proxy where it doesn't reuse connections and eventually runs out, but I also read this bug was fixed. Any tips on debugging connections to tomcat or how would I find out if apache is getting bind exceptions when trying to connect to tomcat?

It didn't hit the server limit but I still get this error: > > [Wed May 23 07:30:54 2007] [error] (70014)End of file found: > ajp_ilink_receive() can't receive header > [Wed May 23 07:30:54 2007] [error] ajp_read_header: > ajp_ilink_receive failed > [Wed May 23 07:30:54 2007] [error] (120006)APR does not understand > this error code: proxy: read response failed from (null) > (xxx.xxx.xxx.xxx) > > That means that when ajp_ilink_receive() (actually ilink_read()) tried to read from the AJP socket, it rec'd an error. Could be a network issue. Could be not enough workers on the Tomcat side. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
