One of our servers has given the following error when upgrading to 11.2.1 - Update Completed with Errors

An error occurred when trying to start the C:\Program Files (x86)\Novell\ZENworks\bin\novell-zenworks-configure.bat process: The exit code of the process did not match with success codes.. Check the system-update.log on the device for details.

Here is a bot of the system-update.log file which seems to have the error

DEBUG;;;Starting process: C:\Program Files (x86)\Novell\ZENworks\bin\novell-zenworks-configure.bat Option : -c UpdateServerXMLConfigureAction -c ExternalCASAConfigureAction -c DeployCasaAuthTokenWar -nopause
DEBUG;;;The exit code of the process is -1

DEBUG;;;An error occured during command execution...details should have already been logged

Any ideas ?

The other servers when finished seemed to do a package rebuild which this one didn't do once it completed with errors ?

Cheers in advance
