When there is a crash on a Windows machine with more than one processor, the resulting Application Flight Recorder (AFR) information gets disordered. It seems that while the dsproxy engine is generating the core (copying all the memory to a file) some of the threads of the process are still running affecting the AFR buffers.
Use Virtual Machines with only one processor or attach Quick Connect Virtual Direcotry Server to only one. If two processors are needed, try generating dumps with ds_windump
Waiting for a fix in a future release of Quick Connect Virtual Directory Server
