Hi,
I have two servers that use JBoss Cache 3.0.3. Each server is configured to replicate its states to the other. The bigger server has more memory and thus contains most of the cache states, while the smaller server uses a ClusteredCacheLoader to get cached states if it can't find them in its own cache instance:
Smaller server -> a cache instance
||
|| using ClusteredCacheLoader to get cached state
\\ //
Bigger server -> a cache instance
The problem is, the ClusteredCacheLoader never retrieved any cached state. Turning on trace, I found that ClusteredCacheLoader always returned null if cache mode was asynchronous replication and there was at least one serialization executor. Therefore, I set serializationExecutorPoolSize to 0. This time, ClusteredCacheLoader did attempt to send out remote request, but it ended up getting a replication exception in the response, as the following log shows:
(
CommandAwareRpcDispatcher.java:291) 2009-04-22 19:47:50,151 TRACE responses: [sender=10.210.102.104:45592, retval=[true, false], received=true, suspected=false]
The bigger server didn't have any exception logged, though.
Any suggestion how I should solve this problem? Thanks a lot!
