Race conditions in cleaning up stale locks held by dead members in a cluster ---------------------------------------------------------------------------- Key: ISPN-777 URL: https://issues.jboss.org/browse/ISPN-777 Project: Infinispan Issue Type: Bug Components: Locking and Concurrency Affects Versions: 4.2.0.BETA1 Reporter: Vladimir Blagojevic Assignee: Mircea Markus Priority: Critical Fix For: 5.3.0.Final Attachments: CacheScheduledCounter.java, ISPN-777_output.txt It seems that rollback sometimes does not release acquired eager locks. See attached test program and run two JVM instances on the same machine. Program schedules a task to run every 5 seconds. Tasks simply locks a key, gets the value, increases the value and puts it back surrounded by begin/commit/rollback tx boundary. Steps to reproduce (keep repeating steps until problem is encountered): 1) Kill one running instance. 2) Restart it See attached example output of a run.
