      Hey Jeff,

      Are the MySQL server and Web server on the same box?

        Yes. Linode host. I have checked space on the server and there is no issue there.

          Jeff,

          I am not a mysql guru either but to me this sounds like you are running out of memory from hackers/bored kids. I have seen this on my own servers. You can check your logs, usually at /var/log/mysql ( I believe is the path). Do a [tail -100 mysql.log] and see if you have line after line of something that like (Post Get HTTP from weird IP addresses). When they constantly do their scanning on ranges of IP addresses they can do some weird stuff that stresses your database out. I doubt you are being targeted in any way because they are just hitting everything with constant barrage of scans. I would run MySql Tuner from that link which also has a guide on how to do it. That should help. Good Luck

            In another search I found said to run 'find / -type s | grep mysqld.sock'

            And I got the following results.

            find: /proc/8311/task/8311/fd/5': No such file or directory find: /proc/8311/task/8311/fdinfo/5': No such file or directory
            find: /proc/8311/fd/5': No such file or directory find: /proc/8311/fdinfo/5': No such file or directory

            Not sure what that means 🙂

              I am not sure what that means either. Have you started the mysql.service back up? If you do a [systemctl status mysql.service] from the terminal does it say its active(in green letters) and running?

                That actually sounds like the service is not running or responding to me but do check that with the command above.

                          Hmm I'm surprised your having issues with that much ram. I mean it certainly could be something else then. You have to check your logs to be sure. Main ones to check are your Apache log and Mysql log. I suspect its Mysql that is messing up though. I would run that Mysql tuner as it can't hurt and will only help.

                          Did you check to see if mysql is running and responding yet?

                            Now that I think about it. We resized (downsized) about 2 months ago and I'd like to think that it was around that time (maybe a little later) that this issue showed up.

                              When I restart MySQL I get this:

                              Checking for tables which need an upgrade, are corrupt or were
                              not closed cleanly..

                                Using top would show you the ram usage....

                                  Installing netdata may be of use... I'm still trying to figure out where I might use it.

                                  Others were saying it sends anonymous data back to the developers site... but I don't know if that's true or not. Maybe a flag to disable etc..

                                    Ok yeah that still sounds like mysql just stopped responding and is just sitting there doing nothing. You first error indicates that it is not running.

                                    Try this: [service mysql status] from the termina. Is mysql running and active?

                                      @jmoore It is when I restart the service. and then about 30-90 seconds later it stops again.

                                      @DustinB3403 What do you mean by using top?

                                        Running top from the cli would show you the ram usage, high ram users etc.

                                          To check all your memory at once just do this command from the terminal. [free -m ]
                                          That will show you the current state of your memory.
                                          Top command is just that. Type [top] in the terminal. Watch it for a while then hit ctrl-z to end the top session
