Issue with mxnode after upgrade to 5.1

[Gene Nordahl]

As part of our disaster recovery I have an automated task to export out all systems into an xml file every night using the "mxnode -lf > system.xml" command and copy that file to our DR SIM server.

But when I go to populate the DR SIM server using "mxnode -a -f system.xml" I get the following error:
"While processing an XML file, the following error occurred:
java.lang.String"

Now this worked when I upgraded from 5.0 to 5.1 using the xml output from the 5.0 system, and during previous (pre 5.1) DR tests, but it doesn't seem to work with the xml output from a 5.1 system.

Anybody else seeing this?? Any ideas before I open up a case with HP??

Thanks
