I get similar errors and after that the client locks showing the blue circle and I dont think it syncs the files after that. As far as I can say it happens when I move images from directory to directory. I got this error just before that. Error no app in context Computed md5 hash is incorrect. I have to restart the client to get it working again.

Nov 06 '22 15:11 TByte007

I have same error： Computed md5 hash is incorrect. exif_read_data(): File not supported at /var/www/nextcloud/lib/private/Metadata/Provider/ExifProvider.php#59 and the sync schedule is -xxxxxx files！ same to restart the client to get it working again.

I installed production docker image, version 25 is very buggy

Nov 15 '22 11:11 jcastro

strange, because these errors should be only logged but should not disrupt the file access

@artonge can you have a look ?

Nov 17 '22 13:11 PVince81

As @PVince81 said, this is probably unrelated to the desktop client issue. Could one of you send us the desktop client logs ?

The "locking on blue circle" started happening after the server upgrade. So I dont think it's the client and i dont see anything interesting in the client log. Just the normal updated/created/deleted. But the client locks multiple times a day and the only way to fix it is a client restart. But this error is pretty much always there as far as I can see: "Error no app in context Computed md5 hash is incorrect." and it think the same thing causes : "exif_read_data(): File not supported" I'm just speculating here but It's like something is trying to processes a file which is not still fully received on the server.

Can you share the full error of "Error no app in context Computed md5 hash is incorrect." ?

My action before was to rename an image file *.png in a folder in an external fileshare. I think renaming a file in the same space or moving it from one to another does not make any difference to trigger this issue.

my whole log says:

Nov 21 '22 06:11 chrissi55

Computed md5 hash is incorrect comes from the bulk upload plugin, so it is probably not related.

Nov 21 '22 11:11 artonge

Append info

I can reproduce the "ExifProvider.php line 59 - Errors" by uploading any kind of images *ico; *png; *jpg ... Other filetypes are (for the moment) not part of the nextcloud error log, as far as i can see.

For new users of 25.0.1 to me it appeared as NETWORK ERRROR 99 in the Desktop client while snycing. A downgrade to 24.0.7 solved the problem

Nov 22 '22 07:11 k-ham

What's the best way to downgrade to 24.0.7?

Nov 25 '22 12:11 ZoltanAB

Same here since Upgrade from NC 24.0.7 to 25.0.1

Nov 30 '22 06:11 FlimFlam

@artonge do you have any recommendations on what needs to be changed i can test and create a pull request of you show me the light ;)

Dec 01 '22 17:12 AndyXheli

Same error with a new instal on ubuntu. Nextcloud 25.0.1 PHP 8.1 Error: exif_read_data(): File not supported at /var/www/nextcloud/lib/private/Metadata/Provider/ExifProvider.php#59

Dec 03 '22 06:12 ghost

Hope this error is one of those that made the Upgrade to 25.0.2 posponed to the 08.12.2022 and is (maybe) fixed in upcomming 25.0.2 :-)

Dec 03 '22 08:12 chrissi55

I've noticed that if I re-save one file (Python script in the last case) too quick (I had to make small changes) and the client locks at the blue circle quite often.

Dec 03 '22 16:12 TByte007

@artonge do you have any recommendations on what needs to be changed i can test and create a pull request of you show me the light ;)

Honestly no idea yet, it would need more debugging to understand what's going on. A few question that could help me:

Are both errors occurring during the same requests (same request ID) ?
Is it happening only with desktop sync, or also when uploading through the web UI ?
Is it happening for every image upload, or only with small files ?

Dec 05 '22 09:12 artonge

@artonge on my side i can answer:

Web UI too (i don't even have Desktop Client)
It seems it produces on small images (here attached the one producing the stack below, on PHP 8.1)

Please note that $fileDescriptor is null here.

I am having the same error. I have my root storage that is an external storage (SMB) and I think it might be the reason. Everytime I upload an image I get:

"app":"PHP","method":"PUT","url":"/remote.php/dav/files/xxx/Photos/DCIM/Camera/IMG_20221209_144628.jpg","message":"e xif_read_data(): Error reading from file: got=x3FFA(=16378) != itemlen-2=x4974(=18804) at /var/www/html/lib/private/Metadata/Provider/ExifProvider.php#59"

Thus the new images don't appear in Maps. However a maps:rescan-photos works so the job created per image is able to access the file while the upload hook is not.

Can't you just schedule a job for the new files so it gets scanned at the next cron execution ?

I have the same issue, docker image and "normal" storage. I do notice that this comes from pictures in my case from a iphone

Dec 16 '22 21:12 gmeks

Me too, fresh 25.0.2.3 install from today, using the docker image, with mariadb. Fed it 50 gigs of data and walked away, came back to only 20 gigs uploaded and a lot of this in the error logs. The client had stopped syncing, but restarting it shook it loose.

@artonge do you have any recommendations on what needs to be changed i can test and create a pull request of you show me the light ;)

I was running into an issue with a new nextcloud instance (server release version 25.0.1). In my past nextcloud instance I didn't face that issue. I suspect that somewhere in lib/private/Metadata component something is going wrong. Lot's of changes in there compared to release 24.0.7 and error logs refer to that component. Files are not changed between releases 25.0.1 and 25.0.2; thus expected that other users still report issues in current 25.0.2 version.

One hint if one wants to reproduce the issue: Do bulk upload with tons of new files (they may be small, to me the issue was on various file types) and keep an eye on the memory consumption of the client (mine is on Windows, consumed all mem that it got).

Btw: In the meanwhile I temporarily bypassed the issue by disabling bulk upload in the server config file ('bulkupload.enabled' => false) with drawbacks of not bulk-uploading any more.

So there are two things mixed here apparently:

Sometimes the process does not seem to be able to access the file in question
The exif_read_data seems to error out instead of throwing an exception. If an exception was thrown, we would only see a warning "Couldn't extract metadata for <...>" in the logs (see: https://github.com/nextcloud/server/blob/master/lib/private/Metadata/Provider/ExifProvider.php#L62)

For the latter: is there a reason not to use Imagick for this job? It seems to be much better in extracting this kind of information and also supports more MIME types - I for example get this error on every WebP file I have:

I resolve this issue by re-pull and re-deploy the container image. This error occurred after I updated the ubuntu system and rebooted the system.
