Good news! I was able to use the system property from ISPN-83 and remove the FLUSH from the jgroups config with 4.2.1.FINAL, and start-up times are much much better. We have a replicated cache on about 420+ nodes up in under 2 minutes. I am seeing an issue with the distributed cache though with as little as 5 nodes. <BR>
<BR>
In the coordinator log I see <BR>
<BR>
org.infinispan.distribution.DistributionmanagerImpl: Detected a view change. Member list changed.......<BR>
org.infinispan.distribution.DistributionmanagerImpl: This is a JOIN event! Wait for notification from new joiner <name><BR>
<BR>
In the log from the joining node I see:<BR>
<BR>
org.infinispan.distribution.JoinTask: Commencing rehash on node: <name>. Before start, distributionManager.joinComplete=false<BR>
org.infinispan.distribution.JoinTask: Requesting old consistent hash from coordinator<BR>
<BR>
I jstack'd the joiner, the DefaultCacheManager.getCache() method is waiting on org.infinispan.distribution.DistributionManagerImpl.waitForJoinToComplete() and the Rehasher thread<BR>
is waiting on:<BR>
<BR>
at org.infinispan.util.concurrent.ReclosableLatch.await(ReclosableLatch.java:75)<BR>
at org.infinipsan.remoting.transport.jgroups.JGroupsDistSync.blockUntilNoJoinsInProgress(JGroupsDistSync.java:113)<BR>
<BR>
Any thoughts?<BR> <BR>
