APPLIES TO
- Microsoft Exchange Server 2003 Enterprise Edition
SYMPTOMS
Consider the following scenario:
- You run Microsoft Exchange Server 2003 on a server cluster.
- You configure Secure Sockets Layer (SSL) on the Exchange virtual server for Microsoft Outlook Web Access.
In this scenario, you notice that the LSASS.exe process reaches a very high handle count after many days. Eventually, the cluster node runs out of kernel resources. And, you must restart the cluster node.
CAUSE
This problem occurs because the Exchange Exres.dll component does not release system resources after it is finished with these resources if SSL is configured on the virtual server.
