All,
We are using JBossCache as means of distributing/replicating session state across a
cluster of application servers.
We use the "CacheMode">INVALIDATION_SYNC . To my understanding, using this
cache mode, the actual cache state exists on only one server and all other servers
maintain a placeholder for an individual entry. If a server attempts to get a cache entry
which it only has a placeholder for, it forces a replication to occur. The cache entry
replicated to the server requesting the cache item. The original server holding cache item
is reset to be a placeholder and life goes on.
What happens when the application server crashes, who is holding the actual entry state
information. It appears the other servers, holding placeholders complain and throw
exceptions.
Is it possible to force JBossCache to automatically remove stale entries; those whose
state is stored on a faulted server
