Master cluster core dump after duplication task running some times.

1. What did you do?
   This coredump occured in an online cluster. We begin running a duplication task and after a few days, and some nodes begin coredump.

   We can see that some error happened when duplication checking a plog to load(a staget of duplication).

Program terminated with signal 6, Aborted.
