             Summary: Timeout on synchronous XSite backup can hang thread
                 Key: ISPN-2992
                 URL: https://issues.jboss.org/browse/ISPN-2992
             Project: Infinispan
          Issue Type: Bug
          Components: Cross-Site Replication
    Affects Versions: 5.2.5.Final
            Reporter: Erik Salter
            Assignee: Mircea Markus


A thread can hang processing a synchronous XSite response if the decremented timeout value goes negative. 

This scenario can occur if backup site A takes a while in returning, exhausting the timeout value. Any subsequent backups can wait on a negative value.  If the response never arrives from the JGroups layer, like due to a bridge end restarting, the future will wait forever.
