Upgraded to GW2014 R2 HP1 two weeks ago from GW2012 SP4. Since the upgrade there has been hundreds of undeliverable errors on the GWIA. The error is "Fatal Error processing inbound message 616e". Seems to be with messages which have many recipients. Has been an SR opened but frontline are just pushing around logs, and do not appear to be doing much. Also tried upgrading to SP1 last weekend, but problem is still occurring. Person handling the SR is requesting the MIME files but there are none. Please need assistance to get this resolved ASAP.
