I am using mod_jk 1.2.30 which I built from the source tarball. My application just locked up so I did a tail -f on the mod_jk log and made a request to it. Here is what generated in the log: [Fri Jun 18 15:30:17.614 2010] [394:47652193829632] [info] ajp_connection_tcp_get_message::jk_ajp_common.c (1230): (tomcat) can't receive the response header message from tomcat, network problems or tomcat (127.0.0.1:8009) is down (errno=11) [Fri Jun 18 15:30:17.614 2010] [394:47652193829632] [error] ajp_get_reply::jk_ajp_common.c (2055): (tomcat) Tomcat is down or refused connection.

[Fri Jun 18 15:31:19.711 2010] [394:47652193829632] [info] jk_handler::mod_jk.c (2618): Service error=0 for worker=tomcat I took a look at the tomcat catalina.out and do not see any errors there. The CPU is empty and the RAM is available. I telnet to 127.0.0.1 port 8009 on the machine, I get a connection, so something is listening on the port. If I do a ps aux | grep java, I see two processes for tomcat which is normal. I checked the mysql log and do not see any errors. I did a show innodb status and do not see any deadlocks in the database. I am attaching the properties for my jk configuation and a screen shot of the JK Status in case it helps. What is really strange is the JK Status page says -48 connections. It seems like that number should always be positive or zero but not negative. I appreciate any help you can offer.
