I noticed that sometimes a specific file can't be recovered. It says that it can't read file x at record y. This seems to be related to nsrmmd crashes that also makes the tape to be marked as full. It looks like this:

Jun 10 17:42:24 britt root: [ID 702911 daemon.notice] NetWorker media: (info) restarting nsrmmd #4 on britt.qbranch.se in 2 minute(s) Jun 10 17:43:06 britt root: [ID 702911 daemon.notice] NetWorker media: (info) restart of nsrmmd #4 on britt.qbranch.se cancelled Jun 10 17:43:30 britt root: [ID 702911 daemon.notice] NetWorker media: (info) SAIT-1 tape 008068S1 was being written before crash Jun 10 17:43:36 britt root: [ID 702911 daemon.notice] NetWorker media: (info) read 2858 records, and EOF marks after file 392 Jun 10 17:43:57 britt root: [ID 702911 daemon.notice] NetWorker media: (info) restarting nsrmmd #8 on britt.qbranch.se now Jun 10 17:43:57 britt root: [ID 702911 daemon.notice] NetWorker media: (info) nsrmmd #8 on britt.qbranch.se started as requested

Then, when reading data on those volumes that have been reported as being written before the nsrmmd crash can't sometimes be read completely. The drives report the following:

NetWorker media: (warning) /dev/rmt/3cbn moving: fsf 430: drive status is The end of data was reached

Could this be due to the bug in nsrmmd that the patch LGTpa69733 is supposed to fix? I have just replaced the nsrmmd with the LGTpa69733 one in order to see if this problem will keep occuring, But it would still be interesting to get feedback if anyone else is seeing this, and if/how it was fixed.
