1951226 - Sybase Unwired Platform - SUP Upgrade 2.1 to 2.2 fails at Messaging Server migration

On customer production system the upgrade fails at the very end of the whole setup routine when the messagging server is upgraded.

This is the errormessage displayed:

According to the logs, where is an OutOfMemoryExepction when the
DBUpgrader.exe tries to convert/sync the QUEUED_MESSSAGES database OBR table at D:\Sybase\UnwiredPlatform\Servers\MessagingServer\Data\OBR.
The QUEUED_MESSAGES.adm is 17GB large and the QUEUED_MESSAGES.add is 1.2GB large.

After using the packtool customer was able to reduce the size from 17GB to 2.7GB. But still the upgrade fails with the same error. It
looks like 2.7GB is still to large.

Upgrade from SUP 2.1.x to 2.2 (Sybase Unwired Platform)
