uff - if i m not completley off then pd itself eats about 30k per second.
its version 39.1 on G4 minimac - no lib loaded - no patch loaded

i m watching the pd process with top on a terminal - it just constantly
counts up the rsize value

best

e

ps - i ll look for newer versions

Try the -noaudio -nomidi flags if you don't need those. I think there might be a memleak in the portaudio code.

I use 0.37-4 for long term installations. That's the last version I found without significant issues on the Mac.
