Hi again,

At least for some of the issues up there I discovered the culpruit - I was using MySQL replication with two master write notes replicating to each other, and when I did a big delete (1000s of items) on one of the nodes, something bad happened causing the replication to pause between the database servers. This caused some of the behaviour I mentioned, but doesn't account for all of it - the Share dashboards not updating on both nodes still occurs (I have lodged a bug for this a while ago but no responses yet).

Anyway, leaving the post up there for posterity and Google.

Cheers,
Johan

Hi, I have a similar problem. I have investigated and my MySQL replication seems OK.
However, I found a JGroups issue, my nodes are not communicating and not joining the cluster. I created a topic here :

Can you look if you are experiencing the same issue?
