Database Locking

[ghost]

I'm receiving the following error when using the acd_cli upload command, or doing any sync is there a reason this keeps happening that I'm unaware of? I'm using latest acd_cli version

[CRITICAL] [acdcli.cache.db] - Error opening database: (sqlite3.OperationalError) database is locked [SQL: 'PRAGMA table_info("metadata")']
Traceback (most recent call last):
  File "/usr/local/lib/python3.4/dist-packages/sqlalchemy/engine/base.py", line 1139, in _execute_context
    context)
  File "/usr/local/lib/python3.4/dist-packages/sqlalchemy/engine/default.py", line 450, in do_execute
    cursor.execute(statement, parameters)
sqlite3.OperationalError: database is locked

The above exception was the direct cause of the following exception:

Please run acdcli -v init to find out where your cache path is and then run fuser <CACHE_PATH>/nodes.db to find out if another process is locking the database.

Did you have multiple instances running? If so, this issue might be a duplicate of #124.
