We use a Linux virtual server.
The server has two applications installed that use MySQL, plus plesk.
Apparently, there was plemnty of Disk space and RAM memory available
The websites as well as access to plesk has suddenly stopped working.
After restauring a backup from few hours before teh crash, we were able to access pleak again, but the websites do not respond properly.
Further investigation points to the fact that the MySQL DB may be the main problem.
Since the server is a production server, we urgently need to restore its correct functioning (by monday, during the morning).
The selected professional should be able to diagnose the problem, and apply the appropiate configurations/changes so as to resolve the problem (also document the changes made is a must).
In case the correct functioning could not be reestablished on the current machine within the alloted time, the professional will need to restore the DB that corresponds to the websites on another similar machine for which we will provide.
