Apparently you've already figure out that there's only one WU involved. When a WU is deleted, whether intentionally (which is strongly discouraged) or by the software (as in: "Client-core communications error: ERROR 0x0 ... Deleting current work unit & continuing..") no failure record it returned to the server, so it gets automatically reassigned.

I'll mark this topic for follow-up.

If you have not already moved on to another topic, you'll need to delete it manually (in spite of my statement about "strongly discouraged")
* Stop the client
* Delete queue.dat and the \work folder
* Reconfigure the client to use a different Machine ID
* Restart

If you want to know why bruce recommended manually deleting the WU, please read about the Bad WU section 2 -> viewtopic.php?f=19&t=16526

What I meant by "all these bad work units" is how many I've gotten lately.

I never delete a WU without a valid reason. In this particular case, the WU kept getting client - core communication error at 40%. Although the text indicates the program was deleting that WU amd getting another, it never did. The program continued in that loop five times. At that point, I determined it would be better to stop the client, delete work files, get another WU and report this particular one.

I know deleting unprocessed WUs is strongly discouraged. But if a WU keeps erroring and looping at the same point, without ever getting another WU to process, I don't see how letting that program loop continue would serve any good purpose. I'm doing my best to contribute as much as I can to this fine project.

As far as the client was concerned, it was deleting the WU and getting a new one. It doesn't know that the server is reissued the same WU.

There were multiple failures so I have marked it as a bad WU. Thanks for your report.
