I am new here, although I've been using max/MSP for a little while.

I am trying to create an environment in which sound is recorded continuously, for a significant length of time (a number of days, at least).

I don't need any info on specific objects or anything... this is my question:

Are there any problems with running max continuously? Am I going to run into problems simply because I am expecting max to run permanently for several days? Does anyone have any experiences of running patches continuously and for significant lengths of time?

Furthermore... recording continuously. I am assuming that, if sound is to be contnuously recorded, it will need to be broken up into seperate files every so often. Is there a sensible limit for how long I should record audio into one file, before moving on to a new file?

Apologies if I've contravened any forum ettiquete by bursting in here with my question.

Max shouldn't be a problem, but some objects may use more and more 

But recording soundfiles shouldn't be a problem.

It's anyway a good practice to restart your computer once a while

Your OS probably has a file length limit. Isn't it 2GB on MacOSX (or 

was it under MacOS9) ? So you should indeed break your files.

And anyway, in case of a crash, you may recover more datas if your save

Max shouldn't be a problem, but some objects may use more and more 
memory and never release it...
But recording soundfiles shouldn't be a problem.

It's anyway a good practice to restart your computer once a while 
(every week or so?)

And anyway, in case of a crash, you may recover more datas if your save 
short files.

I have done a lot of overnight recording on my MBP and found there is a file size limit. 2GB rings a bell but I can't remember for sure. If you are going to build start and stop recording into your patch I recommend using the cputimer object. Here is a little patch I made that starts a new file every 50 minutes. It only does 10 files, but that could be changed.

Andrew, sorry if I'm being stupid, but how do I get the patch from that code?

wow,
thankyou both very much.

How long can Max run/record for continuously?
