We have installed following software on our server [login to view URL] the project is built with maven. So u should have knwoledge about it. it uses streaming quotes from zerodha kite. [login to view URL] The problem is the program takes up lot of physical memory as the day progress. Suppose the program was started around 9.15 am and is using 88 MB RAM at 12.30 pm it uses 214 mb RAM and the CPU shoots up to 98% usage and the program gets killed/stopped out. The program has a websocket implementation using jetty to get live quotes from stream server. Now we think the websocket threads are not getting closed or the program doesn't manage it properly. We have a ubuntu 14.04 64 bit server with java 1.8, tomcat 7, mysql. The code should be built on our server after your fixes. Only Individuals should apply, NO companies Pls.
