When i want to connect to my first node with multichain i've this error :

IO error: lock /home/[user]/.multichain/x/permissions.db/LOCK: Resource temporarily unavailable.

I've just follow this tutorial :

And i can't connect to my node.

Command i've used :

multichain-util create x

multichaind x -daemon

And when i execute this commande : multichaind x@ip:port

i've this :


MultiChain Core Daemon build 1.0 alpha 28 protocol 10007

IO error: lock /home/[user]/.multichain/x/permissions.db/LOCK: Resource temporarily unavailable

ERROR: Couldn't initialize permission database for blockchain x. Probably multichaind for this blockchain is already running. Exiting...

Can you help me please ? It seems to be a stupid mistake.

Thank you !

You need to execute the second multichaind command on a separate system, not on the same system on which a node is already running.
