Hello.
I've found something strange in one AIX system while using "topas"...
I can see the following output from topas:

As you can see, there's a process owned by "oratest" with PID 113654 on
top of process list using 21.4% of CPU resources.
The fact is that if I look for that PID (using "ps -ef | grep <PID>" or
" ps -akfe | grep <PID>" or anything else...) I cannot find thas process
ID.
The same thing is happening with PID 80408 (backbyname): this morning
I've finished some backup operation (but it had finished).
I don't understand what could be happening. Does "topas" uses some kind
of "cache"? Can be something corrupted?
Well, thanks in advance
Ignacio
