Increased memory usage during JBoss EAP buddy replication state transfer

Solution Verified - Updated -

Issue

  • The following exception is found in the JBoss server log:
ERROR [org.jboss.cache.buddyreplication.BuddyManager] Caught exception handling view change org.jboss.cache.CacheException: java.lang.OutOfMemoryError: GC overhead limit exceeded
  • Killing one node in a cluster results in "OutOfMemoryError: GC overhead limit exceeded" or "OutOfMemoryError: Java heap space" on the remaining nodes.
  • We captured a heap dump and the bulk of the retention is in a single AsyncViewChangeHandlerThread, which holds it in a byte[] and/or an ExposedByteArrayOutputStream.

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 4.x, 5.x
  • Clustered configuration with buddy replication
