Networker/NDMP backup problems

Hi All,


I hope someone can help with this; I am having some annoying backup
problems. My backup server is prematurely marking tapes as full
sometimes with as little as 10 MB written. Also, some tapes have
nothing written to them and are rejected by Networker. Errors are
reported in /nsr/logs/daemon.log and are reproduced below.
