Wallet hangs while syncing. Stuck on same mo/day/min/sec

I am syncing my wallet after returning from a trip and it is stuck on FeB 12 06:49:24 2018 and will not process any more blocks. I am running Ubuntu and need to know how to recover wallet and coins.

Is there enough free disk space?

Found the issue - the NiC died. Hanging due to no data from network. NIC is integrated so I moved to another PC and installed the backup dat file and all is well. Thanks for your reply and my apologies for “cockpit trouble”.
