My Bitcoin Core was showing "no block source available..." This is a new problem, I have not changed firewall or router configs since it was working last. I am showing 17 connections, 9 in and 8 out. I have been stuck at 3 weeks behind for over 24 hours now. I am at block number 371276. Please help, I foolishly sent money to one of my addresses assuming that it was catching up.

I am using Bitcoin Core v.0.11.0.0 and am running on linux.
My debug.log is repeating the message "ERROR: AcceptToMemoryPool: non-final"

I am now in the process of reindexing and it is progressing.

Thanks.
