Doing this, I've noticed that the memory used by the radiusd process continually increases, until the system is out of memory, a clear sign of memory leaking. So I kept experimenting and I got quite sure there is some memory leaking. So I tried with Valgrind, and here's what I got after 1 minute (approximately 75 access requests):

  Hmm... I don't see that here.  Maybe try the v3.0.x head, which has a number of fixes.

  No misconfiguration should case it to leak memory.

  No, it's definitely in our code.
