 * I received this error message in my debug file this morning and wanted to know
   how bad of an error this could turn out to be:
 * [18-Apr-2019 19:13:40 UTC] PHP Notice: session_start(): ps_files_cleanup_dir:
   opendir(C:\Windows\temp) failed: Result too large (34) in C:\inetpub\wwwroot\
   wordpress\wp-content\plugins\custom-sidebars\inc\external\wpmu-lib\inc\class-
   thelib.php on line 145
 * My website has not crashed or anything like that. I just want to stay on top 
   of my debug and know what this error message means so when my boss asks me about
   I have a good idea of why this happened.

 * Hello [@npiper](https://wordpress.org/support/users/npiper/)
 * Hope you are doing well!
 * This is a notice that doesn’t affect the site performance in any way. Session
   temporary files are created in the /temp/ folder. It is possible that PHP might
   not have enough rights to work with that folder and remove files.
 * Without the permissions to delete files in this directory PHP is unable to remove
   these files as part of its normal session garbage handling process and so they
   accumulate when they are no longer needed/you will occasionally see this error
   whenever garbage collection is performed.
 * Please make sure the folder permissions are 755. You can even try to set a new
   Session folder for temporary files by adding this line in the php.ini:
    `ini_set('
   session.save_path', '/path/to/your/folder')`
 * Hope this helps!
 * Cheers,
    Nastia
