During a multi-stream restore, the child stream running on one of the non-master media servers might default to using another drive. In the following example, media server bsrv4 should have mounted tape BR5002 and used drive b4-lto3-d1. However, the NBU scheduler used drive b3-lto3-d1 and media server bsrv3, which was busy with a tape already mounted from another stream. This resulted in a deadlock situation.
