problem with database error

[Sarteck]

Your server, which includes your forum. If your forum database is too large, that could be the cause--in that case, your only hope is to upgrade your server to one with more space.

Do you have command-line access? A good way to find out the largest files on your server (if you do) is to run the command
sudo du -a / | sort -n -r | head -n 10
That will give you the ten largest files. If the Logs are filling up your space, you could probably safely delete them.
