getting this error...Warning: mkdir() [function.mkdir]

Does anyone know what this means?

Warning: mkdir() [function.mkdir]: File exists in /home/grove/public_html/core/fn.fs.php on line 114

and how do I get rid of it? The error seems to come and go.

File/Folder permissions on /var/cache/ or /var/compiled are incorrect.

Clear your cache and see if it happens again.

If it does, contact your webhost to fix it or a trusted developer.

Thanks Jesse, I’ll give it a try. Only way to know is wait it out since it comes and goes.
