Thanks for your finding!

I've over 100GB of free disk space.  I don't think there is bad sector error, but I can scan and check.

Previously, I'm installing the Bitcoin core 0.12.1 from scratch, with an empty wallet.

Anyway, I'm going to reinstall it and try again.

Feel free to drop me message if you think of anything I can do.

Thanks! ...Andrew

Here is the debug file:

Thanks!

I've physical 8 GB ram.  But running on 32-bit Windows 7, it use only 4 GB of it.  The debug file is 104MB large, should I post it here?  Thx!

I just installed Bitcoin core 0.12.1 yesterday, and then started to sync.  However, it always stuck at 2 years 45 weeks, waiting for hours and still there.  I've tried reindex, delete the index, using the "prune" option.  But it is the same.  I'm using Windows 7 32-bit.  Thanks in advance!
