you need to make sure that 

1) the number of allowed open files is 1024 by default in /etc/system
(ie the safe maximum under sol 2.6 or lower) and the highest possible
setting is also set.


2) the ulimit for the process (a root cron job in my case) is set high
enough ('ulimit -n 1024' im my case)

here's my cron job that I run every hour (or greater if needed) to
collect and update the graphs for 4 machines
.mirror is from http://src.doc.ic.ac.uk/packages/mirror, but can use
rsync or something else if you want. It just copies the orcallator
output from the hosts to the display host.

ulimit -n 1024

. /export/home/tmgh/.profile
export PATH=/usr/local/bin:$PATH

# Mirror sites
/usr/local/bin/mirror/mirror /export/home/tmgh/bin/orca_mirror_package

/usr/local/bin/orca  -o -v /usr/local/lib/orcallator.cfg
