For the past few days I have noticed that none of the tasks in process by my 4 hosts are shown in the overall task list, even if I select "in process" instead of "all".
Only if I choose a specific host and then select "in process", the tasks are shown.
Also, many finished tasks are missing in the overall list as well as in the list for a specific host.
So, for example, the list for host 483182 does not show any task for Feburary 27, although this host normally crunches about 15 tasks per day.
What's going wrong? What happens to these missing tasks? Did they not end up where they are supposed to end up? In other words: did I crunch them for nothing?

Tasks are not shown in a descending order of sent / received date.
The tasks from February 27 are on the 10th page (at the time of posting this) for your host.

thank you, Zoltan, for the clarification.
I did not bother to scroll back that far - you did it for me - many thanks, anyway :-)

Strange system tough; I don't remember that it was like this ever before, or am I wrong?

You may be comparing this project with others, running more recent versions of the server and website code. The newer versions do indeed show tasks in date order, with the most recently sent at the top of page 1.

Richard, I have started with GPUGRID several years ago, and ever since my tasks where listed in a descending order, datewise. Until a few days ago.

I don't think we've ever had 310,500 tasks - all created over a short period of time - before! The newer BOINC servers do have an explicit 'order by' clause in the underlying query, but here I think it simply depends on most tasks being auto-generated after the completion of an earlier task.
