hi all! from time to time i'm using pd for installations and therefore runing -nogui. it seems that this option causes the cpu-load to explode after a while (some hours or so), which is a bit uncomfortable for exhibition-situations. i was searching the list-archives and found some similar questions (e.g. miller+smoerk around 03/12/02) , but no solution or explanation to this problem. any hints or suggestions? regards d13b
ps: found that problem with pd0.32 - 0.36, oss/linux, -rt ...
Hi!
I don't have any explanation/solution, sorry.
May I ask if you are experimenting any or more drop outs when the cpu-load is exploded?
I use a nqpoly~-based granulator with high polyphony and the cpu load is not always what I may expect. The strange fact is that I can ask PD to perform approximately the same amount of work even when the cpu load is jumped up. Before it jumps it obviously goes up and down following my activity, so I though of some waste of cycles somewhere in some object after it has been "activated" but I never performed debugging or profiling and I never looked at the implementation of several objects that I use in this context.
But maybe this is completely unrelated and I don't use -nogui.
Regards,
Maurizio Umberto Puxeddu.

yes, the sound is a total mess (distorted and clicking), and i have to restart pd.
btw: i'm allready using netreceive in my patches. that was the only hint by miller i could find on the list:
Yes, if you run -nogui, put a "netreceive" somewhere in your patch or else the scheduler gets sick. Why, you might ask, but it's too ugly to talk about

Hi all,
I'm suspicious that the ALSA drivers and Pd get mad at each other after prolonged use (perhaps not on every possible soundcard.) So if you're using ALSA, try it in OSS emulation; this might help...
(I note from other letters that some people get this, and others dont, but I don't know how to figure out what the differences come from.)

I'm not using any sound card. I run the patches with -nosound. I'm just using the mp3 stream to an icecast server on the same machine. So unless that in itself could be the cause, though I don't understand why, it's not a soundcard issue (or is it?) The machine I'm running the patches on doesn't even have a soundcard.
