VC Agent "error formatting page for display"

[MC Murphy]

On the CMS monitoring my servers; the CMS itself shows Software Version Status MAJOR. i click through, but VCA shows "Error formatting page for display." I pick the LOG tab and see a vcagent task showing message "An error occurred while parsing XML Data." Here's the additional data pasted below. How do I fix?:

XSLTTransform::applyTransform - SAX Exception!
