Thanks Howard, I wonder why I didn't find that myself in the JIRA... :-/ The fun thing is, we are definitely not clustered, it's a single ESB inside a single AS going to a dedicated postgres instance. Do you think this is harmful, i.e. we really need to update (i.e. patch the ESB :-/ ), or is it ok to rely on the retry mechanism ? Thanks, Cheers, Tom.
