When MySql starts as a service, The error I get is "access Violation at address 1002593 in module 'LIBMYSQL.dll" Read of address 00000000.

Please help. It errors every 2 seconds and it is frustrating :?:

After doing an exhaustive search at most of the MySQL authoritative addresses for a solution to this issue there doesn't seem to be a definitive answer anywhere to be found.

Here is something you can try that may help fix it for you:

Stop any XAMPP modules and uninstall any XAMPP services you may have running for now - you can always re-install the services after.

Check that there are no processes still running by using the Windows Task Manager selected from the context menu after right clicking on the Task Bar - there should be no apache processes and no mysqld processes showing in the Processes tab after you have stopped every thing and closed the XAMPP Control Panel.

Open xampp\apache\bin\php.ini file in your text editor and find these lines
Code: Select all
; Allow or prevent persistent links.
mysql.allow_persistent = On

Change to look like this
Code: Select all
; Allow or prevent persistent links.
mysql.allow_persistent = Off

Save the file and restart Apache and MySQL

Another method is to do this as well as the above edits:
Drag and drop into your text editor xampp\mysql\bin\my.cnf (it may just be called my)
Find this section
Code: Select all
# The MySQL server

Add this to the section
max_connections = 200

Save the file and restart MySQL

Always make backups of conf and ini files before editing.

Please post back if this fix works for you so it might help others with the same problem.

Not much else I can suggest, so I wish you luck with it.

When installing Xampp with mysql ran as a service off the bat doesn't prompt you and ask if you'd like that service unblocked through your windows firewall. Good idea to do that first.

Actually as long as I tried to run it as a service its then that it would generate the error.

Unfortunately for Mysql to work it has to be ran as a service. It appears every time I click the admin button in the Xampp control panel to check the mysql settings it sets off the error message.
