I am having a problem in which Logic Pro X continually gives me a 'Volume XXX Full' error. It happens after running okay for a while, then I click Play or Record and I get the error. There seems no way to clear this fault, and therefore I am forced to shut down Logic, restart it, then it works again for a while, but soon I get the same error. I am not sure if this is consistent, but it seems to happen when I am moving the playhead location around to different places to listen to different spots in recorded tracks. I am running new (late 2013) Mac Pro with Logic audio files located on an external Thunderbolt drive with over 1 TB of free space. Any ideas for solving this issue?
