Here is what I did to reproduce this:

Deploy clusterjsp.war example on a cluster with 2 nodes with the following
modifications:

- add distributable directive into WEB-INF/web.xml

- remove sun-web.cml

- put random varlues into the session, about 5k worth.

After a while, the session gets lost with the following error:

[#|2011-10-10T20:36:09.789-0400|WARNING|glassfish3.1.1|org.shoal.ha.cache.command.load_request|_ThreadID=33;_ThreadName=Thread-2;|LoadRequestCommand
timed out while waiting for result java.util.concurrent.TimeoutException|#]
 

 

[quote=mk111283]Looking into this. I have tested the replication module by
having 16 threads trying to write and read data with asyncreplication set to
false. In that scenario, I DID NOT see any data loss or degradation in
performance. I am about to test the replication module using JMeter and
cluster.jsp app. Will post the response in the next couple of days. Thanks,
