CAUSE:
The protrace file shows that the database failed when calling our shmVerifySegment function. This function is used after a shared memory segment is attached to verify that it has our magic number in it. The dbname.db file became corrupted when the due to an Operating System crash.
FIX:
Perform an OS backup of the database in its current state and then perform the below:
1. Rename the current .db file.
2. Perform BUILDDB on the database:
PROSTRCT BUILDDB <db-name> <ST file>
3. Proserve the database.
