I would appreciate a feed back if all possible.

Thanks,

I believe it means the MySQL server has run out of disk space. Your database size might come off your hosting disk quota, it might not. Check how much disk space your host control panel says you have left and clean up if necessary. If looks like you have plenty of space then you need to talk to your host ASAP.

Thank you Christian. I did check that's what it was and it is taken care of.
