MySQL error.log out of control

Hi,

I recently started experimenting with creating a MySQL DB using InnoDB tables. I recreated one of my existing databases and then altered the tables to be InnoDB. This was about two weeks ago, and I have done little since.

I noticed today that my /var/log/mysql/error.log file was filling up the volume at about 1.2 GB. The following lines are repeated ad nauseam.

InnoDB: Unable to lock ./ibdata1, error: 11
InnoDB: Check that you do not already have another mysqld process
InnoDB: using the same InnoDB data or log files.

Any ideas of how to fix this?

I deleted the error.log file (and recreated it), but have not been able to reclaim the disk space. I will be restarting the mysql service when there is less load on the server in a couple hours, and hope that will do it. I also deleted the entire cloned DB with InnoDB tables.

Thanks, Josh
