I have created one app using node.js and mysql (AMAZON RDS) as database. recently I have one strange problem with mysql. some of my stored procedures are calling multiple (2-10) times but I have sent single ajax request for the same. I have not seen any error on node. and most of the time this will happen when my app has in its pick time. There is no loop/cursor in this stored procedure, and I am using pool for mysql connection. How do I trace, how it's happens? any guess?
