Hi all,

I'm seeing the following error (followed by service shutdown) on the blockbook services (for ZEC and BTC -- all the others I've tried setting up are working fine):

Apr 09 08:20:47 SCP-BB-ZEC01 blockbook[21477]: E0409 08:20:47.000194 21477 blockbook.go:183] internalState: database is in inconsistent state and cannot be used

The corresponding backend services is/are syncd up to the latest block height (although, ZEC backend reports "progres=0.999998" most of the time, the height looks fully syncd).

I've tried removing the blockbook DB and restarting the service (multiple times), i.e. rm -rf /opt/coins/data/zcash/blockbook/db - to no avail: the error is reported after what seems to be a random number of bulk block connects.

I'm running on Ubuntu 18.04, with a very recent commit of BB source. Docker is from sudo apt install docker.io.

Any inputs would be very much appreciated. I'm successfully running eth, dash, vtc, ltc and others -- only zec and btc are giving these problems. I've also successfully fully sync'd a BTC BB node on an earlier commit of the code.
