I transferred a few mBTC and completed a successful backup and restore test of the wallet.dat. Everything was working fine for a couple of hours and then Bitcoin-QT crashed with a fatal error. Upon restart my wallet appeared completely empty. \r\n\r\nI'm running OS X Yosemite 10.10.2 and Bitcoin core v0.10.0\r\n\r\nSince I had a backup, I'm fine. However from what I see in the debug.log file is pretty concerning. Would this have been recoverable if I didn't have a backup?\r\n\r\n2015-02-28 18:22:42 Misbehaving: 176.31.180.139:53844 (20 -> 30)\r\n2015-02-28 18:23:18 ERROR: AcceptToMemoryPool : inputs already spent\r\n2015-02-28 18:23:36 ResendWalletTransactions()\r\n2015-02-28 18:24:03 receive version message: /bitcoinseeder:0.01/: version 60000, blocks=230000, us=85.229.246.215:8333, peer=125\r\n2015-02-28 18:24:04 ERROR: AcceptToMemoryPool : inputs already spent\r\n2015-02-28 18:24:12 receive version message: /Satoshi:0.8.6/: version 70001, blocks=345566, us=85.229.246.215:8333, peer=126\r\n2015-02-28 18:24:22 receive version message: /Satoshi:0.8.6/: version 70001, blocks=345565, us=85.229.246.215:8333, peer=127\r\n2015-02-28 18:25:35 receive version message: /bitcoinseeder:0.01/: version 60000, blocks=230000, us=85.229.246.215:8333, peer=129\r\n2015-02-28 18:25:56 ERROR: AcceptToMemoryPool : inputs already spent\r\n2015-02-28 18:26:04 UpdateTip: new best=00000000000000000754fa6ed7094ba12ac1b979e1ca6968db5b2a04269241e9  height=345571  log2_work=82.333754  tx=61007596  date=2015-02-28 18:25:34 progress=0.999999  cache=17935\r\n2015-02-28 18:26:05 *** System error while flushing: CDB : Error 2, can't open database \r\n2015-02-28 18:26:12 ERROR: ProcessNewBlock : ActivateBestChain failed\r\n2015-02-28 18:26:12 opencon thread interrupt\r\n2015-02-28 18:26:12 addcon thread interrupt\r\n2015-02-28 18:26:12 msghand thread interrupt\r\n2015-02-28 18:26:12 dumpaddr thread stop\r\n2015-02-28 18:26:12 net thread interrupt\r\n2015-02-28 18:26:12 Shutdown: In progress...\r\n2015-02-28 18:26:12 StopNode()\r\n2015-02-28 18:26:12 UPNP_DeletePortMapping() returned : 0\r\n2015-02-28 18:26:12 upnp thread interrupt\r\n2015-02-28 18:26:12 *** System error while flushing: CDB : Error 2, can't open database \r\n2015-02-28 18:26:17 CDBEnv::EnvShutdown : Error 2 shutting down database environment: No such file or directory\r\n2015-02-28 18:26:17 Shutdown: done\r\n"}}
