Another hour spent fruitlessly trying to scan the transaction history for a wallet, at 99% and 28 seconds left admorydb.exe quits and armoryQt says nothing about even a connection loss, it just sits there. I only found in armorycpplog.txt "ERROR - 1486672480: (SwigClient.cpp:61) POLLERR error in readAndWrite", that is just the Qt losing connection to ADB but again - Qt said nothing about it. It will display tray messages about connection to bitcoind being lost but not ADB, which coupled with the ADB's lack of relevant reports, conspires to make these crashes as silent and obscure as possible. Even moreso, when I relaunch everything the history is rescanned from scratch.

dbLog.txt last states "-INFO  - 20:33:49.875: (..\BlockchainScanner.cpp:852) scanned from block #498700 to #499207", whatever it was doing at the time before it dropped and how far it got, and after that nothing. I don't think I have anything more to give.
