Replication Timeouts in Infinispan

I'm working with a 10-node Infinispan cluster used as a Hibernate Search backend. Our servers are running TC server 2.5 (tomcat 6.0.32) on Java 1.6_24. We are using jGroups 2.12.1.3 for handling cluster cache writes from each node, and for multicast UDP transport.

When we launch 3+ nodes in our cluster, eventually one of the nodes begins to log replication timeouts. We've observed the same result whether we configure Infinispan for replication or for distribution cache modes. Although the rest of the cluster remains stable, the failing node becomes essentially unsuable for search.

Our configuration:

Infinispan:

Because this error is so pervasive regardless of our topology or caching mode, we believe we must be misconfigured somewhere. Can anyone recommend a fix?

Turns out we had a version clash between Infinispan and Hibernate Search. If you use Hibernate Search 3.4.1, you must use Infinispan 4.2.1, later versions may not work.
