I just saw a few messages in the BOINC messages file

Your server seems to have assigned me a ghost workunit:

http://www.gpugrid.net/workunit.php?wuid=1513016

My machine does not seem to know anything about this ghost workunit.


Is this ghost workunit likely to cause me any problems beyond not being able to download the next workunit until a few minutes after my current workunit is reported?

The workunit running previously finished and disappeared from my machine. At the same time, the ghost workunit turned into a real workunit and started.

Well, I was about to start a thread with the exact same title, and there it is from 2010.
Presently I have 3 ghost workunits, which never arrived to my host(s), and interestingly the server somehow knows this, as these didn't count to the 2 wu per GPU limit.

e12s43_e1s76p0f351-GERARD_FXCXCL12R_50141_1-0-1-RND5826
The way these ghost workunits appear gives me the impression that they occure when the GPUGrid scheduler is swamped with requests (when a lot of new work becomes available, and lot of hosts are downloading them simultaneously)

I had 4 ghost WUs in the period from May 19th - May 27th. None since (so far).

I currently have 1 ghost wu on my account. My system crashed with boinc in ramdisk
and than crashed 2 more times after I thought I have resolved my problems.
And then again due to power failure. I appologize for the amount of errors.
Hopefully after a long awaited system reinstall no more problems occur.

Is there a way to cancel these ghost WUs?

Is there a way to cancel these ghost WUs?

I currently have a ghost unit on this machine:

The one bold is the ghost, and it doesn't interfere in getting new units up to the limit of 2 WUs per GPU. This computer has only 1 GPU.

When it reaches the 5 day time limit, someone else will get it, and that's that!

I got a lot of them a few weeks ago when my ISP was having problems (which is far too often). Then a few days later my power company went down several times in about an hour and I got a lot more. They showed on the site but didn't affect my getting work. It seems that if a WU starts to DL and gets interrupted it often turns into a ghost.

I have another ghost unit:
