[jboss-user] [JBoss Cache: Core Edition] - CacheException: Unable to fetch state on startup
JBC 2.1CR4 and JGroups 2.6.1, Tomcat/Linux. Initial state transfer fails when the number
of nodes increases over 100, when a cache loader is used (either jdbm or berkeley db.) If
there are 100 or so or fewer nodes, or no cache loader, state transfer is successful.
The following log messages are received:
dev2|DEBUG|2008-03-17 20:42:05,766 Incoming,xxcid,192.168.3.204:5265
