Couldn't initialize permission database for blockchain X (on Mac OSX)

Question

Had this problem before on Mac OSX with v1, and still persists with v2...maybe I am missing something...

compiled and installed and connected successfully to a chain, running commands etc..then I stopped the chain and deleted the folder for the chain details. Now when I try to connect to the chain again fresh it gives this

multichaind tagcash@tagcash.com:3000 &

MultiChain 2.0 alpha 2 Daemon (latest protocol 20002)
ERROR: Couldn't initialize permission database for blockchain tagcash. Probably multichaind for this blockchain is already running. Exiting...

So I check if multichain is running - nothing there:

ps -x |grep multichain
78928 ttys000    0:00.00 grep multichain

I deleted the .multichain directory in home folder, and then ran the connect command again..it creates a new tagcash folder inside .multichain folder, with these files:

multichain.conf    
permissions.db    
permissions.log

The permissions.log shows only this:

2018-03-18 23:17:44.445    Initialize: Cannot initialize semaphore

Kinda stuck now. Any ideas?

Answer 1

We've heard of this problem before, with OS X semaphores. Does rebooting the OS solve the problem?

Comments

yes..rebooting solves the problem - for now just have to make sure I have a terminal up and running all the time and connected to the chain in CLI..

Answer 2

This should now be fixed in both MultiChain 1.0.6 and 2.0 alpha 4.
