Hello,

I have a forum and it's all be going swimmingly. I've had an issue when trying to use the SpamCleaner (or any other action) with a specific user. They have asked for their messages to be deleted, when I try to use the SpamCleaner, I get :

• XF\Db\Exception: MySQL query error [1205]: Lock wait timeout exceeded; try restarting transaction

When this happens, the CPU usage goes up to +90%, the forum breaks and no one can post, reply to anything.

I have accessed Glances and it says that /usr/sbin/mysqld is using up the CPU. I kill it, but it doesn't help...I have to end up restoring the site.

Please can someone help? Thank you. ​
