XWEB: IIS Hangs When User Cancels File Upload from Within Browser (190361)
The information in this article applies to:
- Microsoft Outlook Web Access 5.5
- Microsoft Internet Information Server 4.0
- Microsoft Exchange Server 5.5
This article was previously published under Q190361 SYMPTOMS
When you use Outlook Web Access to send an attachment of a large file (for
example, 30 MB), click "Add attachment now", click Close, and then click OK
to cancel the task, Internet Information Server (IIS) stops responding
(90% to 100% CPU utilization). The file must be large enough, or the link
slow enough, that the client can cancel the upload before the whole file is
sent up.
CAUSE
Exupload.dll failed to test that the client had terminated the task and
looped infinitely.
RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
Microsoft Knowledge Base:

Exupload.dll (Alpha) 5/27/98 10:44a 29,456
STATUS

Access version 5.5.
