MySQL error Adv. Guestbook 2.3

Hi,

I've been running the guestbook for several months with no problems. However, this morning I got the following MySQL error:

MySQL Error : Query Error
Error Number: 1030 Got error 28 from table handler
Date : Sun, August 11, 2002 12:59:20
IP : xxxxxxxx
Browser : Mozilla/4.0 (compatible; MSIE 5.0; Windows 98)
Referer : http://www.speechteach.co.uk/index.htm
PHP Version : 4.0.4pl1
OS : Linux
Server : Apache/1.6.45 (Unix)
Server Name : www.speechteach.co.uk

Any ideas what it means please and what I need to do to fix it. I managed to get to the admin page and everything looks ok i.e. no abnormal posts or anything like that.
Also checked the db server and found a couple of tables showing "overhead" on disk usage and requesting "optimise". I did this successfully but still getting the same error.

Anyone have any ideas please?

Thanks

Seems it was a problem with the hosts db server. Now running.

Sorry for troubling you.....
