PROBLEM SUMMARY: The problem occurs when the following all occur: - DNS misconfiguration causes a VRN link activation to be rejected (CNCT_OUT RSP ERROR for @Dxxxxxx link in the DLC trace) - CS then frees internal memory used for this VRN link - CS frees memory back to the O/S from its memory cache (this does not happen every time) - the O/S memory manager clears this memory immediately. - CS then tries to access the memory just after it has been released.
Code has been corrected to prevent checking the retry logic for the dynamic link after it had failed to actviate.
