Frequent Azureus crashes - java.io.IOException: Input/output error

I get frequent Azureus crashed in 10.4.6 and 10.4.7. A force quit does not work and always need to do a hard reboot. Below is the latest debug log.

It looks like some kind of cache disk I/O error. I have 2 LaCie Mini hard drives connected to my Mac Mini via firewire. Not sure if running Azureus from one of these drives could be causing the problem.

Has anyone experienced this or shed some light on this.
