I'm having some troubles with one of my servers. I've done an application with two servers, one the frontend that grabs the data of server API (Ubuntu server).
Well, yesterday had a lot of visits and the API server stop functioning but:
-I can do stuff in MySQL by SSH.
-The memory usage is ok.
-The logs are ok.
-The bandwitch usage is ok.
-If i restart the server or Apache2, function by some time (3-4 minutes).
And the most important i think if i tries to access to API (Is rest-style with http) it puts me the Firefox error "The connection has been reset".
-Restart the server
-Viewed the logs of Apache2/MySQL
I don't know too much about systems so i don't know what to do more.
