I have a centos 6.9 in AWS which has mysql server Ver 5.6.36

I am facing really big slowness problem with exporting reports and most time it gives time out. the database side around 80G the server has 64G RAM and the mysql is using it all.  

I am not a mysql specialist, so please if you need any statistic just ask me.
I do not know what I have to share.

but in the logs there is two errors. I do not know if these log related to the same problem.

```
2017-08-02 18:22:31 11629 [ERROR] InnoDB: Unable to lock ./ibdata1, error: 11
2017-08-02 18:22:31 11629 [Note] InnoDB: Check that you do not already have another mysqld process using the same InnoDB data or log files.
