Hello,

Could anyone please answer the question why during printing current
system activity ststus with "w" command it lists a few lines then
hangs for 3 seconds and after it lists the rests of lines? How to
investigate and solve this problem?

AIX 5.2, ML_01


regards,
O.

Altogether now:

$ truss w

Truss seems like too much science for a common condition -- I get this
in 4.3.3 frequently and it represents an orphaned telnet session. Do
a ps -ef |grep pts/xx where pts/xx is the session listed immediately
after the delay.

If you ps -ef |grep the Parent PID you should see a telnet -a
process. If you kill this process the ghost session goes away as does
the delay in the "w" command.

Any administrator who doesn't first think of using truss to debug
an hanged process has a toolbox that's one tool short. I have no
problem understanding the output, so for me it's barely science.
