As it usually goes, MAX started crashing today after preforming flawlessly for three days on site. I use old G5 dual 2ghz desktop. osx 5.1.8, MaxMsp 5.1.9, motu 24IO with latest drivers.

The patch is big and messy and it makes no sense to post it.

Max crashes within 1 minute since I turn dac on.

maxmsp-crashing-consistently-exhibition-openin-tomorrow

What can be argued from the crash log is that the crash happens in the saw~ object, in the audio thread - which I guess you know already.

You say that your patch worked fine until yesterday - what has changed since then? Are the different fields in the DSP status as they should be? Bad settings may lead to crashes, especially with 3rd party externals - are you using any?

Finally, what happens if you just remove the saw~ object(s)?

Sorry for being so vague, but it's hard to figure out what's happening with so little information...

thnx, i didn't get the saw bit. will test now, thanx :)

Did you resolve it? Am I crazy or does it say "thread 22 crashed". I don't see thread 22 posted. That'll probably give you a better indication of where the trouble starts.

that is thread 22. i only copied that part, didn't want to post the whole crashlog.

i erased saw object in the end. it is some wierd bug and it was not so important.

all analog video. 24 audio channels control (CV style) modified tv sets. max controls the tv's, three pantilt cameras, video switcher and arduino.
