File Locked, Cannot Delete

[abbasharoon]

Hi,

Thanks for maintaining the plugin, recently I installed the app from the app store on NC 14 installation. Everything went smoothly but there is an issue when trying to delete a file. Either the request for deletion times out or xml is returned stating that file is locked and cannot be deleted. Same happens sometimes when trying to edit a gdrive file in NC.

Error logs only shows following two statements:
fread() expects parameter 1 to be resource, string given at /var/www/lib/private/legacy/helper.php#297

and

feof() expects parameter 1 to be resource, string given at /var/www/lib/private/legacy/helper.php#296

I am not sure where to start debugging it. If someone can guide me in the right direction, I will be more than happy to create a patch and send a pull request

Thanks

same here, the issue also produces a loop that fills the nextcloud log file with super speed, 50 gigabyte until the the server runs out of space
here is the full error log:
gdrive_delete.txt

CentOS7, MariaDB 10, Apache, Firefox
Cache Redis (also happens with Redis disabled)
MariaDB setup according to Nextcloud instructions
Installation path /var/www/html/nextcloud

sudo -u apache php occ files:scan --all produces:

Same is the case for server crashing. I installed the plugin yesterday and getting frequently timeouts today. Note that server is having more than 40gb ram so a timeout event is very rare on my end in normal circumstances

Server Got crashed today. Removed the app folder and now it's back.
To make it more clear, I am using redis & apcu for file locking & caching as well

@Kaennorsing, can you edit your comment up above and put all the code in a code block? You can either surround it all with triple backticks (```) on the lines above and below the block, or highlight the whole code block and press the <> button above the github text edit box. Otherwise github reads the #16 etc and thinks you're linking to other github issues.
