Hi,
is-it normal to have 86% of CPU for wait commande :
ps aux| head -20
UTIL PID %CPU %MEM SZ RSS TTY STAT STIME TIME COMMAND
root 516 86,6 0,0 12 12 - A 02 nov 2088:03 wait
oralfa01 54422 4,6 1,0 68044 39868 - A 09:20:06 2:27 oracleALFA01
If not can I kill it ?
Many thanks in advance.

No, this is not normal. Have you identified the source of the wait? Is it that root process that we can see? If that is the source of the waits, please check what the command actually is using 'ps -xef|grep 516|grep -v grep', and if it is a killable process, go ahead and kill it.

Hi,
Thanks.
I'm under AIX 5 and it does not know x option
ps -xef|grep 516|grep -v grep
ps: Option not known : x
Syntaxe : ps [-ANaedfklm] [-n liste_noms] [-F Format] [-o spécificateur[=en-tête],...]
[-p proclist][-G|-g liste_groupes] [-t liste_termes] [-U|-u liste_utilisateurs] [-c liste_classes]
Syntaxe : ps [aceglnsuvwxU] [t tty] [numéro_traitement]

Ok. We have this :
ps -ef|grep 516|grep -v grep
oralfa01 51688 1 0 14:32:29 - 0:00 oracleALFA01 (LOCAL=NO)
which means that process is not shown . But it is yet shown by ps aux |head -20
ps aux | head -20
UTIL PID %CPU %MEM SZ RSS TTY STAT STIME TIME COMMAND
root 516 85,1 0,0 12 12 - A 02 nov 2296:53 wait
I'm confused.
