JMS Connection limit?

[vanei]

I have a JBoss 3.2.5, running on Linux. I have over 100 clients connecting JMS queues using HTTPIL (somewhere in internet). But many times the client get a error 500 e can't connect. Any idea about the problem? What's the JMS connections limit?

Usually the 500 error sends back some sort of message to the client or generates some sort of error information in the server logs.

I found the problem. I use Apache/mod_jk/Jetty and the AJP listener was configured to accept only 20 connections (threads).
