A full cache can slow Internet searches or cause problems with web applications. Too large a cache can cause your computer to do slow searches through excessive files in your cache instead of getting the file quickly over the Internet. Another problem is that corrupted files saved in the cache can cause unusual and unexpected problems for web apps such as GradeCam. The solution can sometimes be as simple as clearing your cache.
