now something I'm little bit more concerned: I've seen (activity monitor) that pd needs more and more memory. it starts about 2.7 MB and without doing anything it just increases about 20kb/second . after two hours it took about 150 MB memory and was still increasing. this happens on osx 10.3.9 using miller's pd without any patches or libs is this a bug ? do you have the same behavior ?
thanks Enrique

Which half of PureData is causing the problem? Is it "pd" all lowercase (server) or "Pd" capitalized (client) ?

it's the lowercase "pd" , which is going up and up. now it's over 317 MB . wonder what happen when it reaches the limit.

When it reaches the limit it surely just crashes. Depending on what your limit is, it'll swap a lot before reaching the limit.
I can't test it myself because I don't have a mac.
I would suggest running Valgrind but it's a Linux-only program. What would
be a good equivalent to that on OSX? There's a neat program called "Shark"
on the Developer Tools CD, but I don't recall whether it can detect memory
leaks.
Which version of Miller's pd exactly??

I'm not familiar with that, actually I'm not familiar with c-programming compiling etc.

It is Pd version 0.39-1 compiled for Macintosh. on OS X 10.3.9
using MallocDebug i can see that InitializeTimeInfo called from
AudioIOProc in portaudio/pa_mac_core/pa_mac_core.c allocates memory
on each io cycle. this is then passed as a parameter (timeInfo) to a
callback routine. i'm not familiar with portaudio and thus don't know
who is expected to release the memory (pd or portaudio). i guess this
would be the job of portaudio?

Committed a tentative fix to devel_0_39. I can't try it. Could you?

good job ... i'll forward it to the portaudio list ... maybe they can help ...
cheers ... tim
Thanks... fixed in my version. If everything seems to be working I'll put out a 0.38-2 in a week or so.
