Development for LHC@home

Hi,

i'm not getting new Work today and one of my machines shows "Error while computing" as Status.

E.g. Task 3701142

What's confusing me is this Part:

<message>
Der Dateiname oder die Erweiterung ist zu lang.
(0xce) - exit code 206 (0xce)</message>

Yesterday I had valid results on the same machine:

E.g. Task 3700781

Anyone else experiencing this Message on CMS WUs today?

CMS has had problems at the server for the last 24 hours and any work done fails and it will happen as long as you keep your hosts asking for more.
After many Invalid tasks the server will stop sending more eventually (they should do that sooner)

You need to suspend CMS on any hosts you are running those here or at production

Thanks for the information and help.

I'll exclude CMS from the allowed Tasks, let's see what will happen.

Now, 2 days later, i still have the same Issue.

lhcathome-dev: Notice from server
Daily job limit (1) has been reached

Altough CMS Tasks are disabled in my Account. I see that there are only few tasks ready to send, but limiting me to just one task a day is really not what i want to see.

Thanks for the Link. I know the status pages of the projects. Can you tell me where that describes the reason why one of my computers is apparently limited to just 1 task per day and another isn't although they share the same global lhc-dev settings.

Thx.

As a user of LHC-development it is not usual to hide your hosts, but I suppose on the system with quota = 0, you returned too many errors.
As long as you do not / can not return valid results, this quota will not increase, except one a day.
To display the quota for any application: https://lhcathomedev.cern.ch/lhcathome-dev/host_app_versions.php?hostid= .... fill in your hostid.

Oh my bad, it was just set as on all other projects.

The Host-ID is 665.

Just enbaled new Work again and got 1 WU. (The Quota is still 1 for that host.)

Can I do anything regarding the Error Codes of the recent Tasks?

(0xce) - exit code 206 (0xce)</message>

and

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

Last successfull task (on Feb 22nd) for that host was 3700781

nothing (as far i know) has changed on that host since Feb 22nd.

So wie ich schon dachte. Zu viele Fehler zurück gemeldet.
Es ist nicht deine Schuld. Es gibt ein Zertifikatsproblem am CERN.
Am besten planst du die CMS-Aufgabe einmal täglich ein, während alle Kerne anderweitig
ausgelastet sind und pausierst die dann, bis LHC@home meldet, dass das Problem behoben ist.
Sehe: CMS tasks failing

Die windows error codes sind Fehlinterpretationen von Windows.

I gave you that link to show you there is no work to even get as I already said before and nobody else is trying to get any new work because there is none and CMS is still not running here or production and there is no Theory here and no Atlas

Right now all there is at production is Atlas
