Xampp for windows mysql shuts down unexpectedly

Server Config
1

I am running xampp for windows and when I start MySQL it runs for a few seconds then I get ‘Error: MySQL shutdown unexpectedly.’ This is the third time in a month this has happened. I can correct it by re-installing xammp and re-creating the databases and importing the tables but it is a real pain.

I have not even used MySQL today although the server was started (I always start Apache and MySQL when I open xampp) it was fine yesterday.

Restoring a Windows ‘Retore Point’ does not help and the MySQL logs mean nothing to me.

I would really like to know what has gone wrong and how to fix it now and for the future - thanks guys.

I don’t want to spam everybody with the complete log unless I have to but here are the last entries in the error log ‘mysql_error.log’
