When I Shutdown The Zope Server It Shows An Attributeerror

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): File '/Plone/zinstance/parts/i

Solution 1:

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.
