Thanks to Dr. Anthony "Probe" at www.probepak.com and his tool aprobe,
we were able to find the leak. And lo and behold Sun had a patch available on
04/08/2003. Patch number 110389-03.

I'm wondering if other are seeing a problem with the /usr/sbin/cron process
growing in size without limits. I've seen the cron process up to 125 MB in size.
That was on a system running for about 120 days.
I'm running with kernel jumbo patch 108528-19, patch 109007-11 and patch
110710-01.
This is what I get when I do a prstat on the cron process:
prstat -p cron_pid
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
884 root 53M 52M sleep 58 0 0:05.17 0.1% cron/1
I can get the cron to grow faster if I add 10 cron jobs that get exectuted every
minute, that do a "sleep 60".
Sun is of little help.
