I have created a new Droplet with an screenshot of another droplet. Same configuration.
All access are ok, Apache ok but MySQL stops working after a reset and I can´t start anymore.
There is no error in the log file. Checked swap files, space, configuration faile, everything seens to be ok.

Here is the log file:
