And this is a simplified version of my Nagios check script, that checks user's threads (LWPs) and processes.
Does it run on AIX?

Code:

#!/bin/sh
set -f
PATH=/bin:/usr/bin:/usr/sbin:/sbin

limit=${1:-2850}
plimit=${2:-850}

case $limit$plimit in
*[!0-9]*)
  echo "
Usage: $0 [WARN threads] [WARN processes]"
  exit 3
  ;;
esac

check=`ps -e -L -o user= -o pid= | awk '
{++n[$1]}
p[$2]++==0 {++o[$1]}
END {
 for (u in n) {
  if (n[u]>max) max=n[uid=u]
  if (o[u]>pmax) pmax=o[puid=u]
 }
 if (max>'$limit') {print "uid="uid,"max="max}
 else if (pmax>'$plimit') {print "uid="puid,"pmax="pmax}
}
'`
if [ -z "$check" ]
then
  echo "OK: all users below $limit threads"
  exit 0
else
  eval $check
  if [ -n "$max" ]; then
    echo "WARNING: user $uid runs $max threads"
  elif [ -n "$pmax" ]; then
    echo "WARNING: user $uid runs $pmax processes"
  fi
  exit 1
fi

It can only report one user. If two or more users are above thresholds it reports the top user.

killall5

KILLALL5(8)						Linux System Administrator's Manual					       KILLALL5(8)

NAME

       killall5 -- send a signal to all processes.

SYNOPSIS

       killall5 -signalnumber [-o omitpid[,omitpid..]]	[-o omitpid[,omitpid..]..]

DESCRIPTION

       killall5  is the SystemV killall command. It sends a signal to all processes except kernel threads and the processes in its own session, so
       it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d
       directory.

OPTIONS

       -o omitpid
	      Tells killall5 to omit processes with that process id.

NOTES

       killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program.

EXIT STATUS

       The  program  return  zero  if  it  killed  processes.  It return 2 if no process were killed, and 1 if it was unable to find any processes
       (/proc/ is missing).

SEE ALSO

       halt(8), reboot(8), pidof(8)
