I recently created a cache locking mechanism in our system to prevent race conditions. Most of the time, it works just fine (it creates a lock that is released after a certain period of time):
$lockedDriver = Cache::lock('book_driver_' . $driverData['id'], 15);
But sometimes, it causes errors like these:
Unable to create lockable file: /home/backridepal/public_html/storage/framework/cache/data/6a/44/6a441d0a993f4942895df68b5d5cb8d8e439a274. Please ensure you have permission to create files in this location. {"exception":"[object] (Exception(code: 0): Unable to create lockable file: /home/backridepal/public_html/storage/framework/cache/data/6a/44/6a441d0a993f4942895df68b5d5cb8d8e439a274.

So what I did was inspect my cache driver's path (I use file value in config/cache.php by the way). I executed ls -l storage/framework/cache/datas in the terminal to check file permissions and found out that some files are owned by root instead of backridepal. I don't know what's causing other cache files to be owned by root instead of backridepal, I hope you can help me with this one.
Before I asked for help here, I already tried other solutions like running chown -R backridepal:backridepal storage/framework/cache and running sudo chmod -R 775 storage as root user, but the errors I mentioned above still rarely occur.
