Environment

Cause
This problem is triggered by an invalid short_blk being received. When this occurs, the bptm log will show the following:
A short_blk greater than zero will be received during fbu_check_filheader:
09:35:35.907 [6568.3760] <2> 1123532:bptm:6568:nbuhost: [DEBUG] PDSTS: fbu_check_filheader: next_streamoffset=30664, short_blk=456, buflen=976
...after which an UNKNOWN fh_magic is recorded:

Finally, a software error is recorded:
