MTG: OS2 Causes a GP Fault in Async.ovl.exe

ID: Q173099

The information in this article applies to:

Microsoft Mail for PC Networks, version 3.5

SYMPTOMS

When processing mail with the Microsoft Mail Multitasking MTA for Windows NT (NT MMTA) external program, NT MMTA crashes with a system error message:

OS/2 caused a General Protection Fault in ASYNC.OVL.EXE

CAUSE

This error will occur when the external program encounters a mailbag that contains a message which is corrupted. This corrupted message could be in an external postoffice outbound mailbag, directory synchronization mailbag, gateway mailbag, or the inbound mailbag. When more details are enabled for logging mta activity, the Session.log may end with an entry similar to the following example:


   m:\mai\ma.\001.net!agate!biosci!news.stanford..mai error code = 2

Because there is no MAI subdirectory named "MA.", this is the corrupted message causing the NT MMTA to fail.

RESOLUTION

The mailbag containing the corrupted message must be reset or rebuilt. A manual reset using MS-DOS Debug or the Mailq16 utility can be used to fix the mailbag files. In some cases, identification of the affected mailbag may not be possible.

MORE INFORMATION

Use the Mailq16.exe utility that ships in the Microsoft Mail for PC Networks Resource Kit to reset or rebuild the KEY and MBG files for the user. Mailq16.exe is also found on the TechNet CD.
