SYMPTOMS

Excessive memory may be consumed by Microsoft Exchange Server 2007 on a Windows Server 2003-based computer. Symptoms may include paging and more CPU use when memory is being flushed out frequently. This problem may also cause the following symptoms:
  • The application pool resets in Internet Information Services (IIS). Additionally, event IDs 1010, 1011, and 1013 are logged.
  • Microsoft Office Outlook Web Access users must be reauthenticated.

CAUSE

This problem occurs because of Microsoft .NET Framework CLR memory management inefficiencies.
