Hi guys, This is now a fixed bug; http://bugs.mysql.com/bug.php?id=18118 Now I am looking at upgrading from 5.0.15 to 5.0.20a so that this bug can no longer effect our cluster. So I have two questions; How do I 'work-around' this bug in particular during the upgrade process, eg ensure that the buffer overflow does not occur when I shut the elected Master node down? Will minimising transactions on the cluster do this?

Clever question...

all clusterlog info=0

on all mgmsrv's will do the trick.

after you upgraded all your datanodes, you can set it back

all clusterlog info=8

and; I was wondering if there was anything special to look out for that may not work correctly when going from 5.0.15 to 5.0.20a. I tested doing this on a small 2-ndbd cluster and it seemed to work fine, I was just wonder if there was any hidden gotchas in regards to jumping 5 minor releases in one go?

Not that I know of...
