Its 244M SIZE and 108M RES. So 108M of real RAM used here.

Share you configuration, especially maxconn related stuff, the output of
"haproxy -vv" and possibly "show info;show stat;show pools"
from the unix admin socket.
I don't think that its a memory leak, but haproxy its just allocating
what it can according to its maxconn values and doesn't necessarily
free all those buffers when there aren't used anymore.
