I just got through setting up a test environment configured almost exactly like 
this this morning. (On Windows, using Couchbase.) Have you tried pointing it at 
localhost instead of the server name? Can you post your TicketRegistry.xml?

Subject: [cas-user] MemcacheTicketRegistry

Hi,

I need assistance with debugging the error message I am receiving.

My setup is:

  *   two cas nodes running 3.5.2
  *   the two nodes are behind an F5 load balancer
  *   I have memcached-1.2.8-repcached-2.2.1 setup on both servers.
  *   I successfully tested the repcache/memcache successfully retrieving 
stored data between the two nodes (as noted here: 
http://www.howtoforge.com/how-to-install-repcached-memcached-replication-for-high-availability-over-2-nodes-on-ubuntu-11.04)
 .
However, when putting it all together with CAS I am receiving this error:

2013-11-08 12:30:36,143 ERROR

    at net.spy.memcached.internal.OperationFuture.get(OperationFuture.java:79)

I don't know what this means. My ports are opened and I check that my 
repcache/memcache is running.

Any suggestions?

Thanks
