Greetings... Have you also noticed a spike in CPU usage on your Apache server running mod_jk, or your network throughput?
The reason I ask is we've got a similar problem here. We've got a slightly different setup (Apache 1.3.x, mod_jk, Tomcat 4.0.3, Sun JDK 1.3.1 - all on Solaris), but the same symptoms. Basically what we're seeing is sometimes mod_jk and the AJP13 connecter get stuck in an infinite loop spewing data at each other as fast as possible (and always the same data: Tomcat asking for a BODY_CHUNK of 8186 bytes, and mod_jk replying with an empty packet). The problem will only affect one connection at a time from the pool, but will slowly step up one connection at a time. Restarting either Tomcat or Apache solves the problem, but I've not been able to find any info on this either. I've been trying for a few days to replicate the problem on demand, but no luck yet.... Any of this sound familiar?

Hi, I am using tomcat 3.2.4, mod_jk, apache 1.3.x, linux redhat 7.1. The java processes slowly take more and more CPU power. After about a day, java is taking 15% CPU, after two days, about 30% of a 1GHZ CPU, etc. If I leave it running for more than three or four days, everything is VERY slow. Does anyone know why this happens and if it is normal? I have not been able to find an answer to this anywhere!
