SYMPTOMS
In certain situations, the Microsoft Exchange 2000 Server Information Store may intermittently stop responding, or &quot;hang,&quot; when Microsoft Outlook Web Access (OWA) users access public folders on the server. As a result, OWA users may experience delays and slow performance when they work with public folders.



CAUSE
This issue occurs because of sub-optimal performance logic in the mechanism that allocates buffer pages. When this issue occurs, threads that require buffer pages are blocked by another thread that has a pool of buffer pages locked.
