So I saw some strange behavior with this issue when we did our upgrade to CFMX 7 last night. ServerA is the one that is having the problem mentioned below and is the server that I was upgrading. I uninstalled CF 6.1 Ent and then installed a fresh copy of CF 7 Ent hoping it would resolve the problem.
Running on the same subnet is another CF 7 Ent server (ServerB) that has a Coldfusion cluster on it called cfCluster. When I did the upgrade on ServerA I setup a cluster with the same name (cfCluster) not thinking about the other server being out there. When I did that the 2 CF instances on ServerA found the cluster of the same name on ServerB and set themselves up as replication peers. The 2 instances on ServerA also found each other and the cluster worked just fine. I don't really want the two machines to be working together at this point so I figured I would create a cluster with a different name on ServerB so they wouldn't be conflicting. Once I did that, the cluster on Server B still works just fine but now the instances on ServerA won't cluster together and are showing the same behavior seen below. Obviously the clustering can work but for some reason the instances on ServerA can't see each other without the help of an external server. Very strange. Ring any bells of where I could start looking?

If they aren't you may need to set unicast peers. See the following: http://livedocs.macromedia.com/jrun/4/JRun_Administrators_Guide/clusteri ng2. htm http://livedocs.macromedia.com/jrun/4/JRun_Service_Pack_1_Guide/4relnote s5.h tm http://www.macromedia.com/software/jrun/whitepapers/pdf/jr4_clustering_w p.pd f You can add unicast peers under the Cluster Settings for the server in the JRun Management Console.

Everything was working great until our operations group restarted the server and now only one of the instances is being used by the cluster. A working version on our development box has the following entry in the start up log for one of the cf instances: 11/27 10:06:01 info Clusterable service JNDIContextManager discovered ClusterManager on 128.187.184.236:4160, cluster domain: cfCluster (Lookup Service's JINI-ID: eb9cd98d-808d-4a15-84de-ea6693ed33f8) Followed by a bunch of cluster related startup entries. The production server that is no longer working doesn't have this entry or any other cluster related startup entries. The only cluster related entry says: 11/30 11:16:53 warning Could not find valid replication peer- assuming this server is first server running in replication group. The other server in the cluster is running but things obviously aren't getting initialized right. Anyone have any ideas on how to fix this? I've tried adding/removing the servers from the cluster but no luck. Thanks for your help.
