SUMMARY: lsof on t64u 5.1b - no info for PIDs > 65535

Thanks to Kazuro Furukawa, who confirmed that lsof works just fine for
PIDs > 65535. After some testing, it now appears that the problem is
process related--not sure how/why they're getting confused but a restart
of the associated application fixes them right up. I've enclosed the ksh
script I used to test in case anyone else ever runs across this.

Happy new year to everyone on the list. 

#!/bin/ksh
for pid in `ps -ef | awk '{print $2}' | grep "^[1-9]"`; do
  if [[ -z `/usr/local/bin/lsof -p $pid` ]]; then
    # show process; skip [icssvr_daemon_fr], <defunct>, etc.
    ps -ef | grep " $pid " | grep -v grep | grep -v ' \<' | grep -v '
\['
  fi
done

Hi managers--

I'm seeing strange behavior on some but not all of our 5.1b boxes when
running lsof--it returns output fine for lower-numbered process IDs, but
nothing for higher-numbered ones (I'm guessing 65535 based on
experimentation). Other servers run fine. The lsof version is 4.77, and
I've tried all the normal stuff (/proc is mounted, etc.) with no
success. Anyone seen this and have a pointer to a config change or
something?
