AIX: two strange process

I check for top 10 cpu consumer

ps auxww |head -10
USER          PID %CPU %MEM   SZ  RSS    TTY STAT    STIME  TIME COMMAND
root       131076 23,6  0,0  448  448      - A    16:00:59 50:21 wait
root       983070 21,9  0,0  448  448      - A    16:00:59 46:43 wait

I try to kill them

sudo kill 131076
kill: 131076: 0509-015 Il processo specificato non esiste.

Another strange thing

ps -elf|grep wait 

return 0

I don't understand from where those process came from..
