Hi Danielus,
it would be great if you could submit a test case for this - It would
help me fix the issue you're seeing
cheers,
Rob

Yes, kaha persistance stores directly to the disk, but last time
I've checked
it (few days ago) it was still using memory somehow until
OutOfMemoryException, also I'm not sure about kaha maturity.
I was thinking maybe it's possible to implement that if some
producer hits
memory limit on journal store, it can trigger checkpoint instead of
wiating
for scheduled checkpoint.

If you are using the journal with JDBC then the broker needs to keep
around the messages in RAM until the checkpoint (as it needs to write
them to the database); though AFAIK if you are using kaha then the
journal is the persistent store - so AFAIK the broker can evict those
messages from RAM without a checkpoint

It seems, that message spooling for persistent queue messages is
already
implemented long time ago (in 4.0.x). But messages are spooled only
during
checkpoint (which happens every 5 minutes or so).
Is it possible to configure how often messages are checkpointed?
Between checkpoints producers are blocked, if queue is full. It
seems
that
there was some kind of fix, witch doesn't block the producer, but
spools
messages directly to disk. But it was only for non-persistent
messages
right? Is it possible to implement the same in journaled store.
If queue
is
full, instead of blocking producer, put messages directly to
persistent
store, or trigger checkpoint.
I was testing using 4.2 latest snapshot.
