Error reported by file upload server: hadam3p_anz_a48n_2012_1_008561644_0_6.zip] locked by file_upload_handler PID=-1

Of the 3 completed ANZ models on this host, all 3 are reporting this error on 1 or 2 upload files. All files are going to
<upload_url>http://rwah0.rdsi.tpac.org.au/cgi-bin/file_upload_handler</upload_url>

Of the 39 upload files from these 3 ANZ models, 5 are stuck with this ongoing error. All the rest uploaded OK. No pattern as to which files fail upload by sequence number.
Might be that upload handler fails to recover after a transient error on a particular file?

I'll email the project. They'll need to get this sorted fast.

Hmmm. 3.14 am there, so it's going to be a long wait.

This appears to be an NFS file locking issue.
It currently affects about 1% of the files that have uploaded.

The solution would be to stop file locks on the NFS-mounted storage device on the ANZ server, but I am not yet sure of the implications this would have - I am guessing the effect would be minimal, but I am checking with the servers admin.

I also have 2 stuck with the same error getting reported from different machines:

526 climateprediction.net 27-03-2014 04:39 PM [error] Error reported by file upload server: [hadam3p_anz_n7dq_2012_1_008583254_0_1.zip] locked by file_upload_handler PID=-1

This one got a "transient upload error" at 05:17 (UTC + 11 hours) and then has been getting this since 05:30

and

604 climateprediction.net 27-03-2014 07:30 AM [error] Error reported by file upload server: [hadam3p_anz_n7ot_2012_1_008583653_1_1.zip] locked by file_upload_handler PID=-1

This one appeared after a "transient upload error" at 07:26 (UTC + 11) and from 07:30 its been getting the locked file error.

It looks like a common theme, it gets an upload error and then file isn't getting released. Running BOINC 7.2.42 on one and 7.3.11 on the other.

Just to add my voice - getting the same. I did start another thread (sorry), but Lee pointed me to this one.

With the large upload files and the high server load here, broken uploads can easily happen - here on the server, on the ISP or who knows where else those bites can disappear on their way (maybe the NSA eats some too).

The timeout of the upload handler seems to be somewhat longer than the retry delay of the BOINC core client. I had it too lately for a few times, it always fixed itself after some time.

Jonathan re-booted the server some hours ago, and also removed the file locking.
There are still some transient failures, but that will be due to the large influx of data.

All uploads from here finished ok, including one that was stuck for several days.
Thanks Jonathan.

After file locks disappeared still had transient upload failures. I had to dig out the old proxy server and hook it up to the dial up to clear them. Personally I think it's an issue with my ISP and they don't have a clue. Anyway all files cleared as of 2 hours ago. Work units progressing, and I added 2 more machines to help out.

Please don't abort any of the models. The files will very probably upload eventually and everything you've crunched will be of use to the project. The uploads will retry automatically after specified backoff delays and the files will come to no harm waiting to upload. Some people sometimes have files waiting to upload for more than a week or two. Having files waiting to upload shouldn't prevent your computer from receiving new work.

Some of these delays can be caused by the large number of files waiting in queue to upload and the server can't handle the simultaneous volume.

Upload speed here ranges from dialup speed to full available bandwidth.
Sometimes have multiple transient http errors, most uploads no problems.
Could be server sometimes overloaded, could be ISP or local problem.
Last few weeks, all uploads get there sooner or later.
If other than "transient http" please report.
Long experience leads me to say "give it a couple days" and if error message not yet reported, please report immediately.

<edit>>

Also, have seen uploads that get temp http errors restart where they left off, rather than restarting from 0. Is this the newer better CPDN version?

I get the occasional transient failure, and I'm only a thousand miles or so north of the server. And often by the time I notice, it's already well on it's way again.

So, no worries.
