Hi,
Firstly, what we have is a Windows service (Christened: Aggregator ) written in .Net that processes data in real time and is listening to clients (which are flash based) on a port.. and when a tcp connection is made is starts writing data to the client at 4 times a second. This data is used by the flash player to plot an almost real time graph.. we use this to get feedback on some event from users using their mobile devices. Why nodejs? One of the issues we had was the flash clients were not able to connect to the raw tcp socket when the clients were behind a corporate firewall and doing some investigation we found socket.io to solve this issue. We are now able to establish a connection from flash based client to socket.io (nodejs) to the aggregator. Now the problem: When the nodejs app continues running we see a gradual increase in the memory footprint. I added nodetime profiler to see what was hogging the memory and the objects that are taking up most of the space are of type Buffer (native) and Array and I am not sure if this is something internal or I have to change the way I am accessing the ‘data’ event of then net module. Source: The main js file: https://www.dropbox.com/s/k1u0jg8jl3271m1/mainApp.js Js file that had socket.io implementation and is started as child process. https://www.dropbox.com/s/dq1m294xhae70o7/httpChild.js A dummy app that simulates the aggregator server (sends dummy data to the connected clients on a regular interval): https://www.dropbox.com/sh/qtgj9gp0h1g7erz/OeQjp3vBBg Even when I comment out all the code in the net module’s ‘data’ event handler of the main js file I still see an increase in the memory. Not sure if there is a way to dispose the data object received by this event. Any help / advice is highly appreciated.. I am new to nodejs and do not have any experience in C++.. Thanks again in advance for your time. Please let me know if more information is required.
