Seems like there is no work on the back end?

I wanted to add a posting here referring to the EXIT_SUB_TASK_FAILURE topic, but when pushing the "write reply" button it says "can't create post - failed to add post to DB" - what's going wrong?

I have had the same problem for the past few days. However, the tasks run up to several hours before they fail - what a waste :-(
example:
https://lhcathome.cern.ch/lhcathome/result.php?resultid=424706790

same here out of 20 only 2 were validated and completed others all got Error while computing...

so it seems that most of the current Theory tasks are faulty.
Too bad that their distribution is not stopped by the project people.

when pushing the "write reply" button it says "can't create post - failed to add post to DB" - what's going wrong?

One thing that can cause this error is an invalid character in the text, for example an emoji in a quotation.

yes, it seems so. In that post, I wanted to quote the text at the beginning of the stderr containing a very strange character. This text shows up in all tasks that failed.

I try again, omitting the strange character (4th line, 3rd word - I replace that character by a dot):

<core_client_version>7.16.20</core_client_version>
<![CDATA[
<message>
Die Platzhalterzeichen f.r Dateinamen (* oder ?) wurden falsch eingegeben, oder es wurden zu viele Platzhalterzeichen angegeben.
(0xd0) - exit code 208 (0xd0)</message>

Edit: as I can see, it worked - the posting was accepted this time

The symbol is some sort of encoding issue, when the u with umlaut is miss read, its converted to the replacement character (diamond with ?)

I would not think it related to the issue but the code for the forum should be updated to support the moden encoding standards, the forum on -dev is updated for example.

I would not think either that this encoding problem is the reason for the issue with the failing tasks; however: this initial statement in the stderr is shown only in the tasks that failed (which are, as stated before, the big majority).
No idea how all this fits together. At any rate, I have stopped downolading Theory tasks for the time being. Hopefully the problem will be solved one day.

Is there nothing on this since it was first posted? I've had the same problem here, and it is has become very annoying.

In recent days I get computing errors, only 1, 2 tasks without errors. Please make the tasks correctly, only in this project the calculation problems.

this has been the case for quite some time now. And the bad thing is that tasks often fail after rather long computation time - waste of ressources :-(
And too bad that these faulty tasks are still being sent out for crunching :-(

Is this being addressed?

Yes, but not yet solved.
