Actually, we have a monitor to listen the container's status, if the container exited, will call a hook to change the pouch container' status to stopped, i check today, this function works fine.

@yyb196 can you replay this error again?

[HusterWan]

OK, i know the reason, if you first kill the pouchd process then kill then container, the monitor hook will no longer work, so the container's status will not change.

we will fix this problem soon, thanks a lot @yyb196
