7:55 p.m.
Setup: I'm using Java 5 and JBossCache CR2.0 on Linux.
I have two cache instances with their own BDBJE cache loaders configured to
"fetchPersistentState" on startup. This works with a standard STATE_TRANSFER
and also works for STREAMING_STATE_TRANSFERs except when I have lots of cache state to
replicate (about 500MB in this case).
I start up the first cache and it loads the state from its cache loader, everything looks
fine. Then I start the second cache and I can see it contact the first cache to request
an initial state transfer. Here's what the first cache sees when the new cache calls
up asking for the initial state:

I've tried changing lots of my settings based on other forum posts like this one and a
reading of the JGroups documentation but nothing seems to make a difference--I see the
same sequence of events where the new cache decides it's time to leave the cluster:
| DEBUG 17:27.09 [DownHandler (GMS)] STABLE - resuming message garbage collection

I've tried changing my transaction isolation level to make sure there aren't any
lock-related issues here and I'm running this test without any cache clients reading
or writing to either cache so they should be unencumbered and free to exchange state.
I have tested quite a bit with these two machines. They replicate changes properly and
the STREAMING_STATE_TRANSFER works until the data gets too big which makes me think that
something is timing out but I've had no luck understanding it.
