Hello crunchers!

I have a problem:

It's a problem with my client or BOINC server?

HTTP internal server error

It's definitely a problem on the server side.

There has been a similar problem at the SETI site (Message 1021602), but that was caused by obsolete application versions listed in the app_info.xml file, so it's very unlikely to be the same reason here.

Does the error occur also if you set No New Tasks and force an Update from the Projects tab in BOINC manager?

If so, could you identify (one of) the tasks trying to report? Perhaps that would give more hints.

I just saw that the server logs are accessible again, so you could click the "Last contact" link for host 1275368 on the Computers belonging to hoarfrost page after the update, to see if you see messages correlated with the internal error.

Gruß,
Gundolf

Uh yeah, but the problem is

Message 98829 in response to message 98828

Uh yeah, but the problem is that there won't be a report generated as he can't reach the server. The error itself means as much as this: His computer knocks on the door at the server, and instead of being pointed left by the CGI scheduler to where the information is, it's pointed right into a dead-end where there's nothing.

The error is generated by the client (by the libcurl module) as soon as the signal seems to get lost. Is one of the mirrors down, or having problems?

I had a contact to upload & report work at around the same time which went through without a hitch. I think I used the Glasgow mirror, but am not sure. (Is that info somewhere in one of the sched_*.xml files, as I cannot find it so quickly)

Yes, it'is works.

But requests of new tasks failed until I exclude receiving a GPU-tasks in my account. Now works fine:

For the sake of debugging

For the sake of debugging this problem could you re-enable GPU tasks, issue one work request (update project) and make the sched_request_einstein.phys.uwm.edu.xml available to me (post it here, put somewhere to download or send via PM)?

Also the messages "... already reported as success" indicate that the first part of the scheduler contact (reporting results) had been successful and the error happens in the scheduler itself. So there should be a partial scheduler log. Could you post the id of your host?

It should be this one.

I'm having the same problem.

I'm having the same problem. My Task is not able to report home to say that it's done.

It might be worth having a look at the code round about the area where changeset [trac]changeset:22090[/trac] was made: that's the fix which solved the similar SETI problem that Gundolf referred to.

You can select the Projects tab in your BOINC manager, click the "No new tasks" button and then the "Upload" button. That would at least let your client acknowledge the already reported tasks. You'll get messages that the tasks already had been reported, but that's no error.

Since your computers don't have CUDA devices, I don't know where the problem originates, but one of your computers (3201971) obviously has its preferences set to the effect that no disk space is available. See server log:[pre]Request: [USER#509970] [HOST#3201971] [IP 122.164.160.158] client 6.10.58

I dug out the scheduler log of this contact, it looks fine, i.e. the scheduler ran (0.13s) without crashing.

I don't yet know what happened.

Could you post the ID of your host, and possibly the timezone it's set to, so I could look up the corresponding scheduler and httpd logs?
