mod_jk2 problems

Looking at the logs last weekend I noticed several errors caused by mod_jk2. A friend of mine also pointed out some weird error messages showing up when accessing various servlets. These problems were totally random, but were showing up when the servlet was accessed rapidly. The error messages correlated with the log file entries indicated problems in the communication between the web server and the servlet container:

[error] workerEnv.init() create slot epStat.14 failed
[debug] ../../common/jk_worker_ajp13.c(638): ajp13.getEndpoint(): endpoint creation ... endpoint:15 failed

These errors happened with the latest mod_jk2 compiled from source. I ended up installing mod_jk instead, and all these errors went away.
