Our users see this issue intermittently.... over a year after it was first raised and the KB article created. The KB article states a "possible cause" but does not determine a root cause nor a closed final resolution. Steps to resolution include "if" statements, which are not definitive actions to be taken to eliminate the problem.
I've opened Case 01328621.
If you are encountering or begin encountering this issue, please add your support case number to this comment feed so we can relate them all together and assist CA Support in tracking this problem down to a final/closed definitive resolution.
