Thank you everyone for explanation, suggestion, advice and
investigation about this problem, and sorry for late response. I
couldn't handle this problem this week because H/W trouble happend to
host machine last sunday. And while I waited for the host machine to
finish repairing, the problem is fixed with r357253. So today I
updated this VM to r357333 and confirmed update of poudriere jail
succeed without error. But at the same time I faced a new kernel panic
and am investigating which revision causes it. I will report this as a
new matter.
