An issue was reported where a Gen online module being run under the Diagram Trace Utility (DTU) closes the connection to the DTU when a certain number breakpoints are set. From the user's investigation it appears that the problem occurs when the application sends the DTU more than approximately 3KB of data corresponding to the set breakpoints.
The user found that reducing the number of break points resolves the problem.
CA Gen 8.6 Diagram Trace Utility (DTU)
Root cause analysis required user to capture DTU trace for in-house recreation. That was not possible and the user was happy to use the workaround they had found
Reduce the number of breakpoints set.
