Error Message:

The Cluster service failed a validity check on line number of source module name. "text "

Explanation:

Validity checks check a code assumption that some condition is true, and should never appear to the user.

User Action:

If this validity-check error is not documented, and if the assumption that the validity check has found not to be true does not reflect a condition that you can correct, notify Product Support Services with the event id, the line number, and the module name.
