Tapes at an interval are getting freezed
I have noticed two tapes one on 23rd Oct and other on 25th Oct,09 getting freezed due to the same reason in bptm log file:

The tape was also mounted successfully before and used, but this time it got freezed automatically by Netbackup.
Please guide me on what is causing the two tapes to get freezed.
The Netbackup version is 6.0MP5. Tape Library is C4StorageTek.
Please let me know if you have any queries in understanding the problem. Also convey me if you need any more information.

Additional Remark
I also refered http://www.symantec.com/connect/forums/frozen-tapes-what-do and came to know that my Staging jobs are getting failed with error code 96.
Meanwhile I will keep a check on the tapes and post if others are also getting freezed.
which is it?
Have you determined yet if it is the tape drives or the tapes that is causing the errors?
Have you tried doing a verify on the tape?

check tapes for write-protect
Please check your tapes to ensure that they are not write-protected. If they are and you attempt to write to them, they will get frozen. I have seen people write-protect their tapes when they send them off-site and then forget to move the tab to un-write-protect them when they put them back into the library.

Check
Generally POSITION_ERROR mean that drive can't find end of file. (MTFSF command will leave the tape positioned just after that same EOF).
After some test you'll be able to make any suggestions about cause if this behavior.
where is the "FREEZING MEDIA" message?
abhas,
where is the message from the bptm log that has the "FREEZING MEDIA" message?
Also, you mention that there were other jobs that got error 96 which is "unable to allocate new media". What error did you get for the job that mounted this tape?
