I was using haproxy for load balancing my backend servers. I am on  
HA-Proxy version 1.5.2 2014/07/12.  
The problem is that after changing my haproxy.cfg configuration and reloading and restarting my haproxy service i can see that i am getting a “503 service not available”. Now when i look at my haproxy logs, I can see that some of the requests are still being redirected to a backend configuration which was removed long time back , I do not have “DSIS\_DATA” in my configuration (haproxy.cfg ) as of now . I had done reload and restart of my haproxy service. Why are my requests still being directed to the old backend

Check if you have old processes still running.

`ps auxww | grep haproxy`

Yes Sir , that was the issue . I killed all processes and started haproxy service and it seems to resolve the issue  
Thank you!
