> If you have this remote Vinci cas processor (configured to continue in case

> </errorHandling>
> <checkpoint batch="1" time="1000ms"/>
> </casProcessor>
> {noformat}
> 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.
