Hi,

I'm trying to mix together *lots* of audiofiles (in the magnitude of 
thousands).
I use the diskin2 and filelen/filenchnls opcodes.
It seems to work fine, but depending on the overlap (approx. 250) csound 
exits with the error:
"diskinfo cannot open ..."

I suppose this has something to do with the limit of maximum number of 
open files.
Is there any way I can change this limit ?

I'm running csound 5.14 on OS X 10.6.8

cheers & thx,
jan.

Not an OSX user, but on most unices the number of file handles is a kernel
issue.  Some versions allow this to be controlled externally

Now for the experts....

Open a terminal window and type in the following commands:

sysctl kern.maxfiles
sysctl kern.maxfilesperproc

and check what the results are.  On this Snow Leopard build I see
12288 (max files) and 10240 (max files per proc), although for a long
time it was much lower.

You can increase these values with

sudo sysctl -w kern.maxfiles=18000
sudo sysctl -w kern.maxfilesperproc=15000

or other suitably higher values.

These changes will be reset to the defaults upon reboot.

wow, thanks for the ultra-fast replies :)

I have the same kernel values on my machine, which should be sufficient.

Then I found out, that there's also a maximum of open files in the user 
limits, which is set to 256(!) by default.

running 'ulimit -n 4096' solved the issue !
