Using the Value -1 to Disable the New XOG Governor Limit Does Not Work Correctly for XOG Write
Setting the Maximum XML Node Limit value to -1 in CA Clarity System Administration disables the XOG Governor limit. Currently, entering this value causes XOG write operations to throw the following error:
XOG-9060: The system cannot import this instance with the current configuration. Increase the 'Maximum XML Nodes' value in the CSA and try again.
Workaround: Set the Maximum XML Node Limit to 10^15.
