Re: Server down?

uplinger,

See a few of these "server down for maintenance" logged on Sunday, uploads backing off, but after 1 or more retries the uploads would go again by themselves. Work fetch meantime continued.

22-May-2011 07:32:10 [World Community Grid] Error reported by file upload server: Maintenance underway: file uploads are temporarily disabled.
22-May-2011 07:32:10 [World Community Grid] Temporarily failed upload of c4cw_target03_131620057_0_0: transient upload error
22-May-2011 07:32:10 [World Community Grid] Backing off 56 min 11 sec on upload of c4cw_target03_131620057_0_0
22-May-2011 07:32:10 [World Community Grid] Scheduler request completed: got 1 new tasks

In past we were informed it's a way to manage the load on the servers i.e. selfhealing most of the times... patience needed :D

--//--

PS, think to have written an item on this in the Start Here FAQs :?

The issue started around this time:

Couple of hours later still could not get through to site to upload or download work:

No problem with my other backup project.

But had gone to bed by this time.
Befor hand lowered the cache from it's normal0.2 down to 0.05 and updated a few times to cycle through connection debt and to not get flooded with the back up project.
Thanks again for looking into this
Chris.

Re: Server down?

Chris,

I looked at the logs again, and the only mention i have on our side was when your results were returned. Since others appears to have been doing fine during this time, would you be willing to add some debugging to your messages log? I believe this could have been a routing issue or a non-dns resolutoin issue from your ISP.

To do so, you'll need to take a look at this webpage. http://boinc.berkeley.edu/wiki/Client_configuration

It will tell you how to add debug flags to your cc_config.xml file. The flags I would recommend adding are:
<file_xfer>
<http_xfer_debug>
<http_debug>
<file_xfer_debug>

Also, if you encounter this issue again, can you do a tracert server.worldcommunitygrid.org and 129.33.89.134?

Thanks,
-Uplinger

Re: Server down?

Chris,

If you have any questions on setting up cc_config, please feel free to ask. If you post your cc_config that you are trying that would be helpful as well.

Thanks,
