The Microsoft Exchange Information Store service stops responding in Exchange 2003

The Microsoft Exchange Information Store service stops responding after some time in Microsoft Exchange Server 2003. Additionally, users who are currently logged on to their mailboxes may experience slow or unresponsive behavior when they try to access data in their mailboxes. Users who try to log on to their mailboxes may experience time-outs or long delays when they start Microsoft Outlook. If you restart the Microsoft Exchange Information Store service, the problem is resolved. However, the problem occurs again periodically.

This problem occurs if the following conditions are true:

• There are many ODI entries.
• The Microsoft Exchange Information Store runs out of remote procedure call (RPC) threads.
