For the record, because most queries have 5-6 joins here, I always set  
it up to 32MB on production. We don't have more than 100-150  
connections, so it plays well on normal 32bit machine with 4GB.

If what you wrote about hash-join is confirmed by others, than I am  
pretty much +100 for fixing it.

(just my penny).

thanks.
