hi, we have some trouble with our clustered applications. after restarting one of the servers the user gets a commit exception (see below).
i think that this is already reported as a bug, but jira seems to be down... https://issues.apache.org/cayenne/browse/CAY-796 is there something we can do to avoid that? kind regards, peter STACK:
