Hi Michael,
Not sure if this will help or not as this is a linux thing, but perhaps there is something similar in OSX. Under linux there is "limits.conf" which enables configuration of limits in a number of different ways including by username.

My second question is for Radiance users running OSX. I'm having trouble setting the maximum number of open files to more than 1024. I'm running OSX 10.6.8, and there seems to be two ways to change the maximum number of open files - one using ulimit and one using launchctl.
In *.bash_profile* I have this line:
ulimit -S -n 4096
In *etc/launchchd.conf *I have this:
limit maxfiles 4096
sysctl -w kern.maxfiles=4096and in *etc/sysctl.conf *I have:
kern.maxfiles=4096 kern.maxfilesperproc=4096
In a terminal line, when I enter launchctl limit I see this:
cpu unlimited unlimited
filesize unlimited unlimited
data unlimited unlimited
stack 8388608 67104768
core 0 unlimited
rss unlimited unlimited
memlock unlimited unlimited
maxproc 266 532
*maxfiles 4096 4096*Which is good. 4096 is more than the 2306 files I want rtcontrib to talk to at the same time.
But then, looking at ulimit -a in a terminal, I see this:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
*open files (-n) 1024*
pipe size (512 bytes, -p) 1
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 266
virtual memory (kbytes, -v) unlimitedWhich is bad - 1024 is less than the 2306 files I want rtcontrib to talk to at the same time. Its also surprising given that it should be set to 4096 by .bash_profile.
Then when I try ulimit -n 4096, I get this:
bash: ulimit: open files: cannot modify limit: Operation not permitted
If I use sudo, it takes the command, but when I look at ulimit -a again, the open files limit still says 1024, and despite what launchctl limit says, 1024 is the governing number of maximum open files.
Has anyone out there had success setting this in OSX 10.6 or higher? Or has anyone updated to 10.7 (just released today) and had success?
Many thanks,
Michael_______________________________________________
