Not really a jBoss bug, but possibly worth while fixing: When sending a
non-parsable
bmp SQL statement, the transaction it uses seems to never get closed.

I wrote a simple load test which just creates entity beans and invokes a
method on it.
It worked fine for about 16,000 beans - about 100 or so queries where
unparsable (I read
the data from another table containing names and forgot to escape quotes).
Then the client
freezes when invoking a remote method (well, I assume the remote method
never returns). It
still shows up in the log. Other clients against the same server also hang
on method 
invokation - find methods still work fine.

After a long time, the server spits out the following error message
(multiple times)

Transaction XidImpl [ID=257, Global=robertpc/113256, Branch=] timed out.
Status = STATUS_ACTIVE

but the client's are still dead. 

As I said, not sure whether this is worth fixing (btw, this is
jBoss-2.0FINAL).

Also, is there some documentation about jBoss specific performance tuning
anywhere? Stuff
like

- transaction timeouts 
- cache configurations

Any experiences / stuff which made a difference would be nice as well. We
run on Linux
with postgres as the backend and resin as the client.

Cheers,

Robert.
