I get the following dump from using IBMJava2-13 (production version)
running Orion 1.1.38. The wierd thing is that I thought I had been
hammering on it for 30 minutes or so with no trouble. Now this happens
in the middle trying one of our page requests everytime.
Any ideas?
java -version:
java version "1.3.0"

Classic VM (build 1.3.0, J2RE 1.3.0 IBM build cx130-20000623 (JIT

uname -a:

ps. Just tried it and disabling the JIT makes the problem go away.
