The Imap4.exe process crashes intermittently on an Exchange Server 2007 server

The Imap4.exe process crashes intermittently on a Microsoft Exchange Server 2007 server. Additionally, the following event is generated in the Application log::

Event Type: Error
Event Source: .NET Runtime 2.0 Error Reporting
Event Category: None
Event ID: 1000

Faulting application, version <version>, stamp <stamp>, faulting module kernel32.dll, version <version>, stamp <stamp>, debug? 0, fault address <address>.

This issue occurs when IMAP4 clients perform a search on a mailbox that contains thousands of messages that use nonconsecutive the PR_INTERNET_ARTICLE_NUMBER property. In this scenario, the search operation generates a large query. Therefore, the stack overflows and causes the Imap4.exe process to crash.
To resolve this problem, install the following update rollup:
2407025 Description of Update Rollup 2 for Exchange Server 2007 Service Pack 3
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
