Have you perhaps incorrectly configured your SNMP tool to graph the
value as a gauge instead of a counter (I assume that the SNMP module
returns counters)? That would produce a continuously increasing graph.
As to the old processes still running there were some bugs that caused
this issue which have now been resolved. I can't find the specific
version that this bug is resolved in, but I have been affected by it in
the past.
As Joseph asks, what version and OS?

Hi Pete,
What version of Haproxy are you running and on what OS? Did
you build from source or install the prebuilt binaries they
provide? I do not see the same issue on the haproxies we are
running, but I would be interested in the snmp plugins and
scripts you are using to convert to rrdtool. If you can
share them that is. If we could see them that might assist
in figuring out the issue.

I monitor various statistics about HAProxy through a
plugin in snmp, and oddly I'm seeing that the number of
connections as reported by the front-end is increasing
steadily, even though the traffic is up and down (predictably).
This increase in number of connections is also reported
in HAProxys stats page. If I restart HAProxy, the connection
amount restarts from 0 and slowly risese over a couple of
days... although, even though the new process ends up taking
over the requests, the old processes are still running (I
have about 4 now - is that normal?).
See cacti graphs:
Many thanks for any help.
Pete
