> When the corresponding Vinci service is restarted during the CPE execution, the CPE cannot
correctly reconnect the 4 pipelines to the 4 instances of the Vinci service. This happens
only in a multiple processing units environment.
> This is due to the fact that, in case of error, the failed CasProcessors are put in a
list of failed processors and that processors are never removed from this list. The consequence
is the CPE always try to fix the first processor.
> The problem seems to be located in: 
> uimaj-cpe/src/main/java/org/apache/uima/collection/impl/cpm/container/deployer/vinci/VinciCasProcessorDeployer.java
> Patch proposal attached.
