2021-02-20 Scheduler request failed: HTTP internal server error [SOLVED]
Edit: The number of machines experiencing troubles is growing!
---
Since about 8 hours, 2 3 Linux machines of 7 (+1 Windows) are not able to report.
The results are correctly uploaded.
However the results cannot be reported and it is also not possible to download new work:
Scheduler request failed: HTTP internal server error

Even a reboot did not help.
It is very strange.
Cheers,
Yves

Re: 2021-02-20 Scheduler request failed: HTTP internal server error
Hi Paul,
I thank you for the observation. However it seems to be different.
In my case, I have only the "Scheduler request failed: HTTP internal server error" message; nothing more.
It started with one machine, a little bit later, a second one, and 6 hours later a third one.
Since I am currently keeping the buffers relatively small (<1 day), the machines are close to run dry.
As usual, it's occurring during a week-end.
Cheers,
Yves

Yves,

Apologies, more details in original thread here:

Details in log depend on log options, adding optins for http revealed more details.

I am still waiting for Uplinger to come back to me, However, he has been involved in getting the GPUs started on opn so he has been a bit busy, I presume.

I'll keep you posted.

In my case it is only my PC that has the problem. My phone, tablet & laptop are all ok.

However it is down to the last 25% of the last unit.

In your case, have you checked the result status for your uploaded units? Mine have validated. They will not report or fetch new work.

Mike

Hi Mike,
indeed all the WUs have been uploaded and validated.
Because the WUs cannot be reported, it is not possible to get new work.
I will turn on the log option and have a deeper look.
Cheers,
Yves

Until now, it is interesting to notice that the 2 RPi and the Windows 7 machine are not impacted as well as the 2 Linux machines at the second location.

In my case it is a Win7 PC but my Win7 Laptop is not affected, so that doesn't seem to be the reason.

That log confirms also 500 Internal Server Error.
Suggest copy sched_request and sched_reply for each system and send to support if requested.
