Backups are failing for server and review of AppAssure agent logs (C:\AppRecoveryPM.log) reveals the following error:
ERROR 2015-02-19T03:18:19 [28] - Replay.Agent.Implementation.Transfer.TransferDataChannel (RemoteEndPoint=xxx.xxx.xxx.xxx:62484) Sending of volume data at byte offset 0xb9e06000, byte length 0x100000 failed

Restarting server should resolve the issue short term but deeper investigation of memory, pagefile settings, and drivers for storage and network adapaters should be done to permanently resolve the issue.
