[jboss-jira] [JBoss JIRA] Resolved: (JGRP-171) Dist Lock Manager -- doesnt release locks when a node dies

[Bela Ban (JIRA)]

     [ http://jira.jboss.com/jira/browse/JGRP-171?page=all ]

Bela Ban resolved JGRP-171.
---------------------------

    Resolution: Done

done by releasing locks for crashed members. However, the "owner" argument for lock() needs to be a org.jgroups.Address, otherwise the matching of failed members against lock holders fails !

> I wrote a simple test program to acquire a lock on one
> object and release it after a second.
> When I run this program on 2 systems, and kill one
> system immediately after acquiring the lock, the other
> system cannot get a lock on that object and don?t have
> a mechanism to unlock it.
> Please Compile the attached DistLockTest program and
> run on 2 systems, and then kill one system immediately
> after it acquires the lock. The other system cannot
> acquire the lock on that object at all.
