Comment (by AMDmi3):

 I've gathered some socket statistics, and it doesn't show any apparent
 anomalies (e.g. specific sockets with unusually large buffers). There's
 just a lot of sockets with moderately big receive buffers (up to 512KB),
 and these sum up to take a lot of buffer space. The only anomaly is that
 number of such sockets raise quite quickly at some moment.

 ConstrainedSockets seem to be just what I need, thanks. Don't want to
 limit number of sockets for now, since there's no peaks in socket usage,
 it stable around ~6k.

 I'm running tor 0.3.1.9.
