Hello, I am trying to find out if there was any message order bugs on jgroup version 3.5.1.Final. I know its an old version. I have a report with log files that indicate that messages didn't arrive in same order they were send. As this is the base principle for my jgroups communication I am a little bit schocked and wanna try to find out if they may was any error in that direction. And if yes, that it is fixed on current versions. The used protocol stack is pretty default: UDP, PING, MERGE3, FD_SOCK,...

Hello, I integrated a locking protocol into my application and registered a LockNotification listener to my LockService. What I observed now is that the listener is only working fine on 1of2 nodes. I tested this with the LockServiceDemo and used the attached udp.xml channel configuration (default udp.xml with CENTRAL_LOCK2 at top of the stack). Setup is the following: 2 notebooks in same network connected via ethernet direct link and started on each the demo via a shell. Notebook 1: java -cp jgroups-4.1.0.Final.jar...

Distributed locking, hmm... have you seen my thoughts about this [1]? I don't think distributed locks are a good idea. I did read that part several times and thought about the impact for my application. Thx for the hint. At the end I came to the conclusion that the impact is not a problem in my use case. I need the distrubuted lock basically just as some kind of synchronization to prevent problems when the same user interaction is tried on 2 or more nodes simultaneously. It is more an exceptional...

Hello, I am using jgroups since a while (currently 4.0.19-Final) in my application and so far everything is fine. Thanks for this awesome framework. I need to integrate a locking protocol now. I am using the udp.xml with CENTRAL_LOCK2 at the top and started the LockServiceDemo on 2 different notebooks. So far everything works fine. Both notebooks join the channel "lock-test" and I can lock / unlock / trylock as expected. The only point I do not understand is the owner information about a lock. When...
