Hello Andrew,

I can confirm that the CPU usage is <5% and that the precompiled
classes are being used. Lots of messages like
[Loaded (pre-compiled) java.lang.ClassLoader from <no code source>]

I do see messages like this:

DEBUG::Wed Nov 21 11:05:54 GMT-07:00
2007::com.aelitis.azureus.core.networkmanager.impl.tcp.VirtualChannelSelectorImpl::select::586:
  VirtualChannelSelector: No progress for op 1: listener = class
com.aelitis.azureus.core.clientmessageservice.impl.NonBlockingReadWriteService$2,
count = 300, socket: open = true, connected = true
VirtualChannelSelector::select::332,NonBlockingReadWriteService$1::runSupport::82,AEThread::run::69

Perhaps it's related. Which version of Azureus has RedHat packaged?

Cheers,
Shaun
