RQM 6.0.1 - RQM resume test suite execution record resume operation fails
One answer
I did some testing in 6.0.1 with the latest iFix (016) and could not reproduce the error you mentioned
It may be something specific with the scenario you are running or possibly data in your project
There was a defect logged with the same stack trace

It may be that you are running into a variant of the above issue
Your best be is to open a ticket with the support team so that we can document the steps to reproduce and
