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.
2. What did you see instead?
We can see that some error happened when duplication checking a plog to
load(a staget of duplication).
