[OpenSER-Users] OpenSER with MySQL Cluster

hi 
i'm curious about this one. we used to run a dual Openser installation
with MySQL cluster, but this proved to very unstable (on the cluster
side).
is this working fine now? 

for instance, if one of the mysql cluster nodes was disconnected, this
could
lead to complete cluster shut down, and nodes didn't handle reconnect
very
good. 

so, we actually switched to the register replication instead... 

best regards
/Staffan
