All: I have a shared nothing master/slave configuration using ActiveMQ 5.3.1.
Recently the two nodes lost connectivity (see my previous post "Network Connector failures"). 849 messages were published during the 70 seconds when the two nodes lost connectivity. All 849 messages were apparently republished (and were therefore reprocessed) within the next several minutes. If anyone knows why/how duplicate messages might get published and/or has suggestions for preventing this I would be very grateful! TIA, Mike L. (aka patzerbud)
