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.
