Can anyone tell me what this means?

I’m suddenly getting an error message at the top of my store admin section and it’s appearing on receipts that I print from the store as well. Can anyone tell me what it means and how to fix it? I would greatly appreciate it. Thanks!



Warning: mkdir() [function.mkdir]: Too many links in /home7/uniqueg2/public_html/cart/core/fn.fs.php on line 114



That’s the warning I’m getting. Any pointers would be appreciated!
