bitcoind seems stuck bringing a new node online

[stuman2]

Bitcoin Core: Bitcoin version v0.15.0.0-g3751912e8e

            OS: Linux 4.4.0-96-generic #119~14.04.1-Ubuntu SMP Wed Sep 13 08:40:48 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

   Hardware: Acer Aspire 4270Z, 64 bit, Intel(R) Pentium(R) Dual  CPU  T2370  @ 1.73GHz, 3gb memory
                   640GB hd at 82%

     Problem: Bringing a full node online and the progress has stopped at best chain:
                  hashBestChain=00000000000000000044ac6ea4ac31650fb98bc030c741527bbaa7f0fa769208
                  height=478006 date=2017-07-28 19:25:00 progress=0.938731

     Details: Debug.log supplies peer information, but never reaches another new best block. 
                Peer information includes peer's block height>what I show above.
                I had network issues with my ISP last Saturday due to a storm, but have since
                gotten back online.
                This is the bitcoind daemon running on a non-gui Linux install, so there is no screen shot. 
                I get a fair number of "connection refused" messages in the debug.log, but that seems normal as I was getting
                those when building up to this point. 

                It just simply doesn't progress anymore, whether I have port 8333 open or not. (I see no need to open it
                until I have the entire blockchain downloaded, but I have tried both.)

                There are no transactions of mine involved, as this a "new" wallet instance. 
                I won't put any coin into it until it is caught up.

                Some communication is happening as the progress was at one time 0.94xxxxx, but
                has dropped since more transactions have been added to the chain.

                This happened before at 68%, but I restarted the process by deleting all the blocks downloaded and re-indexing.

That is very close to the Bitcoin Cash fork. Maybe your node only has Bitcoin Cash nodes as peers, I don't know. Perhaps try deleting the peers.dat file in the data directory.

Can you post the debug log?

It was cranking up until late July of this year, then stopped.  I did a re-index, which resulted in a log of mostly "new best=" lines up to here.
