I have two CAS 4 servers configured with replicated Ehcache ticket stores.

When both servers are online, everything seems to work fine.  However, when one 
server goes down, the other one becomes essentially unresponsive.  It seems 
like it's trying to find the (now non-existent) replication partner and it 
takes so long that the service ticket expires.

It works like this:

1.       Both servers up:  Log in and get TGT

2.       Drop server that issued TGT

3.       Attempt to access a CAS protected service

4.       The online server just sits paralyzed trying to talk to the 
replication partner for a while

5.       I get a message saying my ST has expired.


I can share my configs if someone has any ideas.  At this point I'm somewhat 
stumped.

Geoff
