"Failed to acquire connection" when running a package from within another package.

I am receiving an error on my master package that executes a number of other packages. The individual packages work fine when executed by themselves. However, I am getting the following error when I attempt to execute it from another package:

Error: Failed to acquire connection "conneciton". Connection may not be configured correctly or you may not have the right permissions on this connection.

Thanks in advance for your help.
