Zope2关闭存在一个问题,该问题试图关闭数据库连接(进而关闭存储).但是,此后期运行序列对RelStorage的用户有一些装饰性的副作用.这很烦人,但从根本上讲不是应该引起任何数据完整性问题的问题.
FileStorage或ZEO的用户不应看到此信息.

I am using Plone 4.3.3 for creating my Plone site but when I shut-down the server it shows the following error.
Traceback (most recent call last):

There is an issue with Zope2 shutdown that tries to close a database connection (and in turn, a storage). However, this late-running sequence has some cosmetic side-effect for users of RelStorage. This is annoying, but not fundamentally a problem that should cause any data integrity issues.
Users of FileStorage or ZEO should not see this.
