Many transaction log files are generated in a short time on an Exchange 2003 Service Pack 2 server

Many transaction log files are generated in a short time on a server that is running Microsoft Exchange Server 2003 Service Pack 2. Additionally, you may experience the following symptoms:

• The size of the database unexpectedly increases.
• Server resources experience a heavy load.
• The Microsoft Exchange Information Store service may temporarily stop responding. This behavior causes a disruption of the messaging service.

This problem occurs if you perform one of the following actions in Microsoft Office Outlook Web Access:

• You attach to an e-mail message a file that exceeds the maximum limit that is configured for your mailbox or for the Microsoft Exchange organization.
• You post to a public folder an item that exceeds the maximum limit that is configured for the public folder.
