[jboss-jira] [JBoss JIRA] (JGRP-1912) LockService can fail under heavy load

[Bela Ban (JIRA)]

Bela Ban commented on JGRP-1912:
--------------------------------

A {{tryLock()}} can always fail (timeout) on high load. So why do you consider this an error ?
If you run with {{lock()}} instead, you shouldn't see any errors. But make sure you want until all workers have completed.

> Once in awhile, the LockService will get stuck acquiring a lock.
> These seems to occur most often when two threads are simultaneously trying to acquire the same lock. (i.e.:  exact same millisecond on a server with multiple processors).
