Ontape Level 0 Archive Aborts Itself....

Hi, Hoping someone can shed some light on the following. We are running Informix ODS 7.24.UC2 on Sun Ultra Enterprise 4000 utilizing Solaris 2.6 We are using an Exabyte EXB-8500 tape drive; 8mm Helical Scan 7GB uncompressed tape. We have the following in our onconfig: TAPEDEV /dev/rmt/0mb TAPEBLK 1024 TAPESIZE 6809600. A few days ago we loaded the remainder of our production data. We were able to get one successful 0 level archive. It prompted for a second tape (for the first time since migration) with no problem. Yesterday we received OS Error #28....no space left on device. The Informix message log states "internal subsystem error...archive aborted by client". It never prompted for an additional tape. The system administrator has reviewed the documentation regarding tape drive, tapes, etc. for our platform and can find nothing specific pointing to a problem. Are we overlooking anything here? Perhaps any bugs of which we are unaware? Would appreciate any feedback in trying to resolve this issue so we can obtain a good level 0 archive. Thanks for your help.
