Just to complete this thread, if anyone searches on it and reads through. We have a few customers left we are trying to get upgraded that still have Quovadx 5.3 and in preparation for their application upgrade, are finally installing Window 2003 SP2. lo’ and behold, upon reboot, CCG fails immediately or eventually fails (site claimed 3 days uptime post reboot). the errors referenced in this thread were exactly what we got.
What fixed it was applying the SP2 patch for 5.3 (We have one for 5.4.1 as well).

The server version changes from 5.3P to 5.3P_Rev5 post-install and runs without errors. I am not sure where you can get this update officially.
