laravel - ErrorException in Filesystem.php

Question

Issue with session storage

Session storage not working with my Laravel 5. Used it for a month without problems. But since latest upload to web server I get the following response on every page.

ErrorException in Filesystem.php line 74:
file_put_contents(): Exclusive locks are not supported for this stream

Many posts on the internet are indicating to remove the reference to

$lock on line 74 in Filesystem.php

Seems like a quick fix which will lead to other issues down the road...

How do I take care of the root cause?
