Probably "phantom" tasks. This happens now and then when there's some sort of overload on the Oxford servers.

Message 55847 - Posted: 4 Mar 2017, 0:43:30 UTC - in response to Message 55840.  

See the thread below (Orphaned Work Units). I have a number of WU's that CPDN believes are active but are not visible in my BOINC application. My best explanation is that there is a BOINC failure processing mode that occurs on my Intel I7 machine where BOINC processing fails, the data and WU informaton is deleted from my machine, but there is no error report to CPDN....

This results in CPDN continuing to believe the WU is being processed, when in fact it is not...and the WU is then not resent to another user until the 1 year time limit on processing has passed.

And a few weeks ago when the trickles were missing, I had a WU that finished and reported with an OK from the servers (on the BOINC Manager Log), but stills shows as in progress... At least now all the trickles appear.
