Hi Rune

You don't have unlimited virtual memory - this in fact refers to the
swap space, so you have as much virtual memory as you allocated to your
swapfiles.  The kernel will tend over time to "page out" any memory
which an application isn't using, so all this is telling you is that
the daemon allocated itself 108Mb of memory which it hasn't used recently.

First question - does the virtual memory usage increase with time, or is
it fairly static once the daemon has been running for a while ?  I have
a similar memory usage although slightly lower - this is after six days
and hasn't increased since I checked after your bug was raised:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
   3370 root      15   0 93352  700  472 S  0.0  0.1   0:59.42 upnpd

I would not be surprised to learn that libupnp3 still has memory leaks,
but the important question is, are they sufficient to cause a problem.
