I’m using TikiWiki with MySQL database for SDTConf and AgileCoachCamp wiki. Recently both these wikis were down with the following error:

On googling about it, I found: “One common cause of this is the disk hitting 100%, so use df and du -sk / to try and figure out where your clogs are.” In my case, I’m pretty sure that I have enough disk space. I’m still not sure what caused this. But I found a work around to solve the problem at hand. If any one has ideas about this, I was be eager to hear about it.

Solution: execute the following command:
mysqlcheck –auto-repair -u{username} -p{password} {database_name} {database_table_name}
