SuspectExceptions thrown during MapReduceTask while removing the intermediate cache ----------------------------------------------------------------------------------- Key: ISPN-4173 URL:

MapReduceTask. I have also seen SuspectExceptions in these logs. This could be related to shutting down the intermediate cache (https://issues.jboss.org/browse/ISPN-4144), so I will check again once this is addressed. If this is the case the fix for ISPN-4144 will need to be fixed in both versions.
