Just noticed error rate has doubled to about 6% in
last 24 hours. Seem to be ERR_RESULT_DOWNLOAD which I
have confirmed my checking MBs right now. Any help/detailed
info welcome while I notify CERN support.
(Another Friday afternoon problem!) Eric.

Doesn't seem to be any pattern on my computers I have 5 identical ones, 3 have errors and 2 don't.

Error is always:

<core_client_version>7.2.42</core_client_version>

There all B1 injection jobs, maybe that batch is bad? Or permissions on the folder with B1 jobs in?

I noticed a few of these during the course of today - a very small, sporadic, problem, with the majority of jobs downloading just fine.

Here's a selection from one of my hosts:

Error tasks for host 9924593

They all failed with

#define ERR_HTTP_PERMANENT  -224
    // represents HTTP 404 or 416 error

and every wingmate (validation partner) also failed to download them: that suggests that the problem is at the server end, with the files either missing or inaccessible to the download server.

All the workunits that I checked were created around midday on Saturday 5 July.

Thanks for feedback; pretty sure we have a server problem indeed.
Usually this is permissions because some daemon was [re-]started
as root or something. Looking at it. Eric.

OK; thanks to your help. I have a whole bunch of problematic
WUs from a new user. All seem to be called w- something.
Doing what I can to identify the issue but may be Monday before
I can solve it with his help. Enjoy the weekend. Eric.

I just found one created a little earlier than all the rest: WU 18788924.

One user downloaded it successfully, but all the others failed.

The second volunteer on that job - host 9649253 seems to be having great difficulty attaching to the project and downloading the sixtrack executable, but that's a different issue.
