Is Java/Tomcat on FBSD practical?

[Heath Volmer]

Thanks for the replies.  

I ran Tomcat as root (or other users, doesn't matter).  What happens
means absolutely nothing to me.

I get on screen: lefty /kernel: pid 22239 (java), uid 0: exited on
signal 6 (core dumped)

This is what I get in Catalina.out:

SIGABRT   6*   abort (generated by abort(3) routine)

If the stacktrace looks like it is some VM issue - posting it here may
help - otherwise the tomcat folks may be a better bet.

One quick test - try running it as root and see if that changes anything
- some JDK version had that problem - which since is fixed if I recall
correctly.

We are using it with no great issue (other than that java can be quite
memory hungry :-)
