Service is hanging up when running in parallel mode with org.apache.uima.aae.error.MessageTimeoutException

[Spico Florin]

Hello!
  I'm trying to deploy a service that should run 2 delegates in parallel.
The service is based on the uima given examples. Please find below the used
descriptors:


<UIMA_HOME>\examples\descriptors\flow_controller\MeetingDetectorTAE_AdvancedFixedFlow.xml
(provided by uima)

<UIMA_HOME>\examples\descriptors\flow_controller\AdvancedFixedFlowController.xml
(provided by uima)
ParallelFlow.xml  (deployment file for uima as made by me, see  the source
at the bottom of this message)

When trying to deploy ParallelFlow.xml  as UIMA service (by
usingDeployService.cmd) I'm getting  warnings and exceptions and after that
the service is shutdown.
Can you please have a look if I did something wrong? Any suggestion is
appreciated.
Thank you.

Reagrds,
 Florin
