Steven, I have to say that's one hell of a good response! I've got some
followup questions for you.

Assuming that you know nothing about Java, how do you go about interpreting
garbage collection or JRun metrics?

I've seen this once, but the crash log didn't make any sense. It referenced
an the JDBC-ODBC bridge that comes with JRun, but that wasn't being used by
any of the CFMX applications on the machine - and that's all there is. I
went through all the JRun server instances, but didn't see any using JDBC
data sources. Do you have any insight on this?

How do you recommend determining this? I've read somewhere that it's a good
idea to set both to the same value; is that what you generally recommend?

Thanks in advance!
