Question:
We noticed in the collector logfile following error message:
 
2019-01-21 13:04:03,741 @collector <collectorScheduler-11> [] ERROR #UpdatedJobsAsApiReader             # An error occured for server waaeprod: JobRepository failure forcing rollback
org.springframework.batch.core.step.FatalStepExecutionException: JobRepository failure forcing rollback
...
...
Caused by: org.springframework.dao.OptimisticLockingFailureException: Attempt to update step execution id=4023 with wrong version (1), where current version is 2
...
...

Is this a problem for WCC?
 
Environment:
WCC 11.4 SP6 
Answer:
Actually this should not be a problem because when this problem happens, the collector automatically retries the collection.
