Well, after 12 hours at a consistent 25kB/sec, you'd expect to have over 1 gig of memory allocated. As you don't, i think what you're seeing is just 'normal usage' for the non-compacting GC that mono uses. I have a similar app which uses sockets extensively (50-150 simultaneous connections) and i can assure you that memory usage doesn't get unbearably large. It'd be interesting to see the logs but i don't think there's much to be worried about.
