Problem starting build on Agent running Ubuntu

Hi,

I have many client running various versions of RedHat Enterprise and Fedora Core...

I have one Ubuntu client that I'm having problems with. When the build starts, I get this error:

WARN - nt.runner.GenericProgramRunner -

The agent is Ubuntu 5.10 "Breezy Badger"
The version of java is 1.5.0_05

There are no errors when the agent starts up.

Thanks,
