[jboss-jira] [JBoss JIRA] Updated: (JBCACHE-1168) Sometimes acquired locks are not released

Sometimes acquired locks are not released ----------------------------------------- Key: JBCACHE-1168 URL: http://jira.jboss.com/jira/browse/JBCACHE-1168 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 1.4.1.SP4 Environment: Windows XP, jrockit90_150_06 Solaris 10 Reporter: Jacek Halat Assigned To: Manik Surtani Fix For: 1.4.X Attachments: jbosscache.log, output.txt, TransactionStormTest.java Sometimes under heavy load acquired locks are not released - node is locked forever. Only what can we do is stop/start cache. Main loop: while (true) { for (int x = 0; x < 2; x++) { WorkThread t = new WorkThread(x == 1); threads.add(t); t.start(); } for (WorkThread separateThread : threads) { separateThread.join(); if (separateThread.getException() != null) { //separateThread.getException().getMessage(); } } int locksNum = getNumberOfLocksHeld(); // System.out.println("Locks="+locksNum); // checkpoint if (cache.getNumberOfLocksHeld()>0){ System.out.println("ERROR, locks="+locksNum); doDomethingOnCache(1); } assertEquals(0, locksNum); } Exception - after //checkpoint line numberOfLocks is grater than 0! JUnit is provided to this issue, but this error is nondeterministic - sometimes fails after 5 seconds and another time after 20 minutes.
