We found it when we were troubleshooting inconsistent connections on the mesh device. The signal level is fairly low at that location, so it's not clear if it actually caused the connection problems. We moved to a dedicated channel, and haven't experienced the disconnection since. It's hard to tell if our clients in the dorms are experiencing issues with this, since reporting is uneven.
