Sometimes aquired 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)
Components: PojoCache
Affects Versions: 1.4.1.SP4
Environment: Windows XP, jrockit90_150_06
Solaris 10
Reporter: Jacek Halat
Assigned To: Jason T. Greene
Attachments: 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.

-----------------------------------
Fix Version/s: 1.4.1.SP8
(was: 1.4.1.SP7)
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: 1.4.1.SP8
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!
