This is known issue, see [1,2]. It is suggested that you use one of
the following:

Command line options for bitcoin-qt
-maxconnections=<n>    Maintain at most <n> connections to peers (default: 125)
-listen                Accept connections from outside (default: 1 if
no -proxy or -connect)

so set maxconnections to something smaller or "-listen 0".

Upstream developers suggest turning off "listen" by using the command
line options or config file. I'll leave this open as a pointer for
others who are interested in it as well.
