I see - the KeyGeneratorWorker executed using the supplied executor doesn't finish until the KeyAffinityService itself is stopped.  When I wrote the KeyAffinityServiceFactory, I was under the erroneous impression that this was a short-lived task - and that all KeyAffinityServices could share a single thread.  I've fixed this in AS7.  You can close this.

> I'm working on scalable ha-clusters and I have a domain-mode cluster in mind which uses Infinispan-distribution to be scalable. So I started to make the cache-containers use distributed-caches instead of replicated ones.
> It starts up well and seems like everything is ok. But when I try to access a stateful-session-bean the server hangs. It only hangs when I try to use a distributed cache for the container ejb. If I use a replicated cache for ejb but still use distributed caches for cluster and web everything works fine. The problem does appear independent from the number of cluster nodes.
> By hanging I mean that the server won't complete the request. It will start to shutdown on CTRL+C but will not finish to. The only way to kill the server is kill -9. Attached to this post there is a file containing the stdout of the server with a thread-dump (kill -3) appended at the point where I requested a SFSB and nothing happened.
