I was reviewing my tasks a while ago and noticed that the page showed only 1 task "In progress". But I had just looked at the active tasks listed by BOINC Manager on my Host 10342612 and it had 3 tasks "In progress" - all were several hours in and showing 30% to 50% complete. Looking a little further, I discovered that the 1 "In progress" task listed on the tasks page was on a different host and that the 3 on Host 10342612 were not listed at all. So I did an Update (see log below) and all 3 were aborted by project:

and then I did another Update to report them.

7/23/2017 4:15:14 PM | LHC@home | Scheduler request completed

After the second Update, I looked at the tasks list again and still couldn't find the 3 tasks.

I should note that I updated to BOINC 7.8.0 several days ago. It is a Development version and has the warning (MAY BE UNSTABLE - USE ONLY FOR TESTING) - so I suspect this strange behavior can be blamed mainly on it. OTOH, considering the recent problems with Sixtract here, there might also be an issue with LHC. I just wanted to make you aware. I will also post a link on the BOINC message boards. I should note that BOINC 7.8.0 has also reported several Sixtract tasks successfully.

I saw the same:

LHC@home 07/23/17 18:53:26 Result LHC_2015_LHC_2015_192_BOINC__2__s__62.31_60.32__7_8__5__60_1_sixvf_boinc807_1 is no longer usable


I'm on 7.6.31 so I think it's a server problem

I had the same done to a windows10 i5 machine. All jobs removed with "no longer usable". Every thing gone...

Thanks fo the feedback. I "accidentally" caused the tasks to be aborted.
However you raise other interesting issues about the server and client.
which I shall leave to the experts. Eric

Mea Culpa, the tasks will come back. Eric.

My main thought was that the new BOINC developmental version had caused a server/client "sync" problem. But Toby's response put that idea to bed pretty quickly.
