      Sure it does; I ran your test program, and after a while it garbage-
      collected and the available memory figure dropped right down. It
      collects (on my system) about once every 40 seconds.

      Hello everyone,
      a couple of weeks ago I upgraded from OS 10.3.9 to OS 10.4.6 (on
      Powerbook 1.33 GHz, 1 GB RAM, still working with Max/MSP 4.5.7). I
      also installed the corresponding driver for my M-Audio 410 Firewire
      interface. Since then it happens from time to time that the DSP
      doesn't start correctly: Although the DSP Status window shows Audio
      "On" CPU Utilization stays at 0% and nothing happens. The problem is
      hard to deliberately reproduce. It appears with completely different
      patchers and usually disappears after restarting Max/MSP while
      opening exactly the same patches and starting them in exactly the
      same way. I thought, it might have to do with using Max after
      awakening from sleep mode, but today (in a live-concert by the way) i
      faced this problem directly after opening Max and it could not be
      solved by just closing and reopening Max - I had to restart. After
      that everything worked perfectly again.
      Has anyone faced the same problem or does anyone have an idea about
      the source of the problem? Has it to do with the OS, the driver oder
      Max itself? Any solutions?
      Thanks for your help!

      Most likely you aren't authorized for MSP, just Max. Send a note to
      support@cycling74.com and we can get you squared away.

      I got my authorization for Max/MSP in 2003 and have been working
      quite a lot with it since then.
      The problem I described never appeared before upgrading my system to
      OS 10.4.6 (including upgrading to the latest audio driver for the M-
      Audio 410).
      Today it happened again and I tried changing the Audio driver to Core
      Audio (leaving DSP on) which actually worked; switching then back to
      the M-Audio driver I got again only silence (DSP status window
      showing Audio "On" and CPU = 0%). After reopening Max/MSP using the M-
      Audio driver everything worked fine again (absolutely the same patch,
      no random functions included, not CPU intensive). So far it has
      happened with a couple of different patches - therefore I don't think
      it is related to the behaviour of a particular object. I guess it
      might rather be a driver problem.
      Has anybody else experienced it?
