That error about file locked by upload handler is a server side problem where a file upload was interrupted in some way, but the server process that was handling it did not terminate. When upload retries for that file occur,, the server thinks the file initial upload is still in progress and the next try gets that error. The solution in the past was rebooting the server, or restarting some processes. Seems like ANZ models used to have this problem a lot with the server in Tasmania, and now the CAM models are favored for this problem.

I'm away from the machine until Tuesday. Will reboot and check then.

Nothing much happening "upstairs".
Is there any improvement with the zips?

Sorry, mine are still stuck

I am sorry to hear that people are getting stuck uploads. I thought the upload situation was going to be fixed before the release of new work?
Unfortunately I am not able to comment in regards to state uploads as I have not been able to get any work. I have .read in another thread there has been Windows work but I was not one of the lucky recipients

My upload fail is still the same:

Interestingly, I am running 4 cam25 models and only this model is currently presenting the stuck upload for the _restart.zip. Other zips for this and other models are going through.

Interestingly, I am running 4 cam25 models and only this model is currently presenting the stuck upload for the _restart.zip. Other zips for this and other models are going through.

I suspect the one stuck while others go through is the file locked by upload handler issue which requires either a script restart or a reboot of the upload handler.

No News about failing uploads ?

I've notified the project staff about the server possibly being down. No response yet.

Still no news?

I guess you may as be abort the ANZ zips.
The Oxford people are busy elsewhere.

You may as well abort the CAM25 zips.

I have only recently started supporting this project again after a long gap.

I noticed that most of the trickles did upload ok but I had 2 zip files that would not for some reason to do with the project server.

I have now 5 wah2 tasks.

I will let these run but have set the project to "no new work" in boinc manager.

It does not seem worthwhile to run tasks when the upload does not seem to work reliably.

From what I read in other places of the forum the communication (internet) is not so reliable for the project and this is the main reason uploads do not complete.

The boinc community activity for this project in running the tasks should be supported with a reliable means of uploading the results.

Maybe one solution is to set up one or more virtual project servers in a good internet coverage location to manage all the distribution and uploads of tasks.

Then the project team could just communicate with this remote location whenever they needed to update the tasks to be sent out and download the results.

Just trying to propose a possible way forward :)

The hung upload files have mainly been for the WAH2 ANZ and CAM25 regions. It used to be the servers for these regions were remote and remotely administered in the countries where the research projects were being proposed and worked on. I'm not sure anymore about that, but it would make sense as to why those two regions have the problems and the others don't.

I noticed this morning after turning my computer on their is a Weather At Home 2 that failed saying the following files were absent I gather these are from batch #845

Another task has been created and sent out so it will be interesting to see whether or not this one fails two

@Speedy The error message in stderr on the task page says "The system cannot find the drive specified.". This is an error that crops up occasionally. No one knows the cause. It's not typically reproduced in the other tasks in the work unit. It may be some kind of timing issue when the model tries to write to, or read from the disk.

The error listing you pasted into your post are just because the model crashed before those monthly upload files are created. It was expecting to upload them and they were never generated. It's unfortunately not useful for finding the cause of the crash.

Climate models have lots of files open, which all need saving at checkpoints.
With your computer having so many processors, it will need a VERY fast HD to keep up with all that saving when it occurs at the same time.

Thank you for pointing this out I have cut it down to working on three tasks at a time. I'm not sure but maybe when I turned my machine last night it was trying to upload a trickle message

Thank you for explaining the error message it makes complete sense. Hopefully I will be able to complete other tasks without them crashing

I've had one cam25 zip transfer failing with 'transient HTTP error' since about Oct 26:
https://www.cpdn.org/result.php?resultid=21743279

Can it be fixed or is the advice still to abort?
