Can you find any incorrect record in each file under /usr/openv/netbackup/db/error?
I tried to edit these log files directly, and with some pattern I got same error. "EXIT STATUS" line is tough, but I find removing job group id causes segmentation fault.
If you can not make sure when each lines were recorded, try this.
# cat file | perl -ne 's/^(*)/localtime($1)/e;print'
