Need help with error

For some reason, sometimes my board has an error. I just now recieved it while logging out. Our hosting company is getting annoyed at the thousands of e-mails it recieves due to this error, so I guess I better fix it. I am running 2.03. Can anyone offer me a suggestion as to what it could be please?
