since fews days Mysql server on Windows does not success on closing itself. In the mysql error log I find multiple instance of these lines:
InnoDB: Operating system error number 32 in a file operation. InnoDB: The error means that another program is using InnoDB's files. InnoDB: This might be a backup or antivirus software or another instance InnoDB: of MySQL. Please close it to get rid of this error.
I have plenty of free space, the server is installed for months, the version is 5.1.22-rc-community-log on Windows XP SP3, and I have used only one Windows account to create and execute Mysql service.
Thanks Cedric
edit : you are both rigth, and ProcessExplorer help me to find another Mysql service with a special name. I kill it and all run fine. Thanks a lot!
