Hi Jeroen,

I never hit this problem for the moment.  
It's possible you hit the Haproxy feature that do not stop directly the haproxy process, but instead spam a new one and let the older(s) continue to deals with opened connections.

If you use Haproxy with TCP connections (such as handling pop, smtp or imap, ftp, etc) haproxy could potentially never ends its older processes. Perhaps it is the cause of your problem ?

I advice to check if your haproxy process has really restarted with
    ps faux | grep haproxy

And try to restart haproxy instead of simply reloading it.

Good luck
