    @wanderson Is that when the issue occurred? This is an abnormal error, I’m just trying to understand the trigger.

    Any other insight you can provide will help the developers come to an answer quicker.

      Apache is not able to answer all requests, would it?

        @wanderson Those “last insert ID” errors are almost always fixed because:

        That said, when updating, you probably need to refresh the page (after ensuring the DB is usable).

          Mind you all,

          the suggestions I give are based on experiences, this is not by any means a cureall for every situation. The lastInsertID might be present from the period of time you were updating the server to begin with, so unlikely to be the problem you’re experiencing.

            Remember, errors and “solutions” are very subjective. One fix will not fix every scenario especially when dealing with different OS’s.

            I gave information based on what i saw in the error, but this does not mean the “suggestion” I gave is going to fix the problem you were having.

            In regards to things, did your server update?

                      What? Why would httpd be down?

                      This sounds like a max_connections issue to me though.

                          I will try to apply this rule in apache

                          <IfModule mpm_prefork_module>
                          	StartServers          4
                          	MinSpareServers       20
                          	MaxSpareServers      40
                          	MaxClients           200
                          	MaxRequestsPerChild  4500
                          </IfModule>```

                            @wanderson Is it giving 500, or is it getting “connection” errors? 500 means apache is responding.

                                Problems began to appear after I started adding more than 20 nodes, I’m currently using 34 fog nodes

                                  @wanderson Maybe too many clients hitting the apache with requests? Please check your apache access and maybe error log to see what’s going on and how many requests from which hosts are coming in.
