I had two instances of multichain running on the same machine, and the machine crashed. I'm now unable to start either of these instances. The error I'm getting is:
me@518781d398a5:~$ multichaind -datadir=/home/me/mc2 chain1
MultiChain Core Daemon build 1.0 alpha 14 protocol 10003
ERROR: Couldn't initialize permission database for blockchain chain1. Probably multichaind for this blockchain is already running. Exiting...
I checked (ps -x / ps -ef), and there's no multichain process on this machine. Is there anything I can do to restart the blockchain, or do I need to create it from scratch?
