David,
What's your memory looks like at the time of error? We have similar
configuration(centos, Mina version), I also encounter server hang. Are
you use direct memory? It is the killler for me. After getting rid of
it, things works much better for me.

Anyone have any ideas?
We're running MINA 2.0M6 on OpenJDK 1.6 on CentOS 5.4.
