Same here with sixtrack and Atlas. I enabled all subprojects suitable for a Windows machine and got 5 Theory and 12 CMS tasks. I was planning to switch from Theory to Atlas for a couple of weeks but that has to wait now.

Atlas-native and Theory-native is downloaded.
There are 2.4 Mio. sixtrack in the pipe. This is quite a lot!

Hi,
sorry for the late reply - just back from holidays.
Do you still see the issue? I have just put online my pc and got 35 SixTrack tasks straight away.
Cheers,
A.

Yes several hours later I was able to get a couple hundred tasks but they are all finished and now it is back to 8/19/2019 10:55:11 PM | LHC@home | No tasks are available for SixTrack

So now I have nothing again.

SixTrack
Unsent - 3109040
In progress - 128470


There must be a reason for this.

Yes, more than 3M tasks in the queue and therefore the BOINC feeder queries take much longer than usual to fill the scheduler buffer to send out tasks. Hence there will be no tasks available from time to time, as the scheduler runs out of tasks. We'll activate a second scheduler like earlier this year, however our bottleneck is the database.

The server status page will be alternating between 2 servers while this workaround is active.

I think the 32547 is equal to 0, as this was the number when they ran out before. My sixtrack only computer is running out of WU and my others have ramped up on Theory and CMS

Hi,
apologies for the wrong number of tasks in the queue - this was due to tasks in the BOINC DB orphans of their WUs due to a WU deletion back in summer.
I have just cleared them out - at the next server status update, you should see that the sixtrack queue has been drained out.
Thanks for spotting this,
Cheers,
A.
