Comment 7 for bug 1080539

The documentation at http://www.codership.com/wiki/doku.php?id=galera_parameters implies that you should set both these values to 512 for WAN replication, so this should probably also be updated.

http://www.slideshare.net/henrikingo/introduction-to-galera also gives the same values.

I had set these values based on this information and experienced a similar crash over the weekend.
