> I was doing some testing with a single MDP listening to a queue which had about 247300
messages, with a postgres backend. ActiveMQ server was started using the default activemq
startup script (on Linux). In this configuration the cpu normally stays mostly idle and I
described this behaviour in another bug report.
> Another issue came to surface when I tried to profile the client application with EclipseColorer
to see why a single MDP can't hog my machine. But when I tried so, 4 OutOfMemoryError messages
were logged by ActiveMQ server. Note that I was *not* profiling the server, but the client
which is a totally different process.
