Debugging an app on WLS8.1 requestTimeout

[Mike Rae]

Does anyone know how to increase the requestTimeout value in Eclipse, or Weblogic Server 8.1 to prevent the current debugging thread thinking the server or IDE is dead and starting a debugging session in a new thread?
The result of this problem is that the debugger jumps back the callstack to where the first breakpoint is i.e. where the debugging began.
I am not too sure if this (happens after about 60 seconds of inactivity) can be configured in Eclipse or WLS. I have scoured the Eclipse project preferences but to no avail.
Any hints or info, or a solution greatly appreciated.
Cheers
