qmtest resource related error

[Siddharth Ram]

I have a question/problem related to resources.

I have defined the following resource. It is supposed to spawn a process 
(named Server) on the local machine with which my test interacts

<?xml version="1.0" ?>
<!DOCTYPE extension
  PUBLIC '-//QM/2.2 - or-changes/Extension//EN'
  'http://www.codesourcery.com/qm/dtds/2.2 - or-changes/-//qm/2.2 - 
or-changes/extension//en.dtd'>
<extension class="process_resource.ProcessResource" 
kind="resource"><argument 
name="delay"><integer>0</integer></argument><argument 
name="path"><text>/test/qmtest-db/orbtest.qms/pytest.qms/servant/Server</text></argument><argument 
name="args"><set/></argument><argument 
name="resources"><set/></argument></extension>

When I run the test, the server seems to start up fine, receives 
requests from the client, but threequarters of the way through the test, 
it crashes with a stack trace as below:
Any help would be appreciated.
Also, documentation on resources seems to be pretty thin.. could someone 
point me to where it might be documented ?

thanks
Siddharth
