On a new installation of Ubuntu 14.04.3 LTS I installed HAProxy 1.5 from trusty-backports.
When I restarted HAProxy, I got random HTTP 503 although the backend servers were all working fine. By checking netstat, I saw that HAProxy was listening multiple times on the frontend ports.
It seems that the init script coming with the installation does not work correctly. The processes are not terminated correctly when using stop (or restart, in this matter, too, which uses the stop function).
Only with a kill I was able to correctly terminate the HAProxy processes.
The following output should show more clarity:
