Bela, Agreed, increasing the timeouts is probably not the way to go. However I am at the mercy of whatever Infinispan is doing. As for the notion of Infinispan being tested at 1000 nodes: Manik was quoted here: http://itmanagement.earthweb.com/netsys/article.php/3864436/Red-Hat-Ramps-Up-Open-Source-Cloud-Projects.htm It was never denied here: http://community.jboss.org/thread/156494?tstart=0 and I'll have to wait until I get home to dig up an email that I think I have. However, I'm not assigning blame, I was under the impression that it had been tested at 1000 nodes. I just had it up at 430 nodes, but I can't reliably get it to that size when I restart it. I think the answer is that Infinispan will have to use what will scale in JGroups (remove what does not scale). Until then I will have to scale it down to a size that I can start in a reliable fashion. Still no answer on whether ISPN-83 will be in 4.2.1.....
