> The full story is user forum under title:
> Activemq 5.4.2 hangs when the temp disk usage is used
> On the line 219 of
> http://svn.apache.org/viewvc/activemq/tags/activemq-5.4.2/activemq-core/src/main/java/org/apache/activemq/broker/region/cursors/FilePendingMessageCursor.java?view=markup
> I unlocked the messagesLock that was created in the queue. I have done that,
> because the writer thread waits for free space, but the consumers are locked
> waiting until the writer thread releases the lock.
> My fixing approach was making the cursors aware of the RW lock.
