    Infinispan EC2 Error - this.merge_id (null) is different from merge_id

    Joe Reger Newbie

      Hi All!

       

      I'm running Infinispan 4.2.1 with Hibernate 3.6.4 on Amazon EC2.  App server is standalone Tomcat 7.  OS is Amazon Linux/CentOs.  I keep getting this error:

       

      2011-05-28 22:30:46,540 [OOB-512,InfinispanCache,domU-12-51-39-00-86-57-34887] ERROR org.jgroups.protocols.pbcast.GMS - domU-12-51-39-00-86-57-34887: this.merge_id (null) is different from merge_id (domU-12-51-39-00-86-57-34887::78)

       

      Cache seems to be working locally but I've verified that they're not updating across the cluster.  EC2 instances are in same security group so I don't believe there is any network block.  I'm using S3_PING and have verified that it's properly talking to S3, storing status files in buckets, etc.  Members of the cluster see one another and adjust the cluster membership roster.

       

      Config files below... based on the ec2 sample file in the distro.  Any ideas?

       

      Thanks!
