Failure during concurrent restart of cache/manager -------------------------------------------------- Key: ISPN-3698 URL: https://issues.jboss.org/browse/ISPN-3698 Project: Infinispan Issue Type: Bug Components: Core API Affects Versions: 5.2.7.Final, 6.0.0.CR1 Reporter: Paul Ferraro Assignee: Galder Zamarreño Priority: Blocker Fix For: 5.2.8.Final, 6.0.0.Final These failures prevent the cache from starting successfully, and consequently the redeploy to fail. There are 3 stack traces of note in the logs: {noformat} 15:05:32,044 ERROR [org.jgroups.blocks.RequestCorrelator] (OOB-20,shared=udp) failed unmarshalling buffer into return value:
