Hi J-D,
You are right, there are other reason causing the server shutdown:

主题: 答复: Disable table causing regionserver shutdown
Nobody asked to shutdown the region server. Only disable tables, but the region
server shutdown.
I have 8 region servers, 2 shut down, the same reason.
Please recheck if there is a problem.

主题: Re: Disable table causing regionserver shutdown
That's the expected behavior when the region server is asked to
shutdown and there's a compaction running, take a closer look at the
log before those lines to find the reason.
