Apache Tomcat and Mod_jk

Question

We have been running Apache with Tomcat using mod_jk for about a month now with out issues. This morning I have started seeing the error below in the mod_jk log files.

I am fairly new to using mod_jk and am not sure how to increase the number of connections, see the number of active connections and/or kill of connections that are idle or dead.

Any ideas/help would be much appreciated.

Answer 1

So it turns out this issue was a by product of another configuration issue. We had different Railo contexts configure to point to the same set of shared directories, some of the context's mapped to directories that were within the root context which caused Java thread locks
