Event ID 54 with Source (HTTP) logged without details of the error message.

The following event appears in the System Event viewer, without any details in the Description field. 

Event Type: Warning
Event Source: HTTP
Event ID: 54
Description:
The description for Event ID ( 54 ) in Source ( HTTP ) cannot be found.

 

Event ID 54 is a Windows I/O manager event corresponding to:

�An Io Request to the device %1 did not complete or canceled within the specific timeout. This can occur if the device driver does not set a cancel routine for a given IO request packet.�

If the Windows I/O manager tries to cancel pending I/O request packets (IRPs) associated with the HTTP.SYS driver, the IRPs may not get cancelled.  Previous to Microsoft Windows Vista, HTTP.SYS did not supply cancel routines for certain I/O operations.  These IRPs not cancelling would cause the Windows I/O manager to write this message to the event log.  The lack of details in the event message is due to the I/O Logging DLL value not being present in the HTTP EventMessageFile registry entry.  This issue is not a security nor a performance concern.
