Operating Systems AIX Vmstat fault section all values are 0 Post 302770307 by MadeInGermany on Friday 15th of February 2013 06:44:19 AM

The many zeros in vnstat are okay.
I assume your second sample is from ps command.
<defunct> with PPID=1 is bad; it looks like a fault in the kernel.
Watch out for a kernel patch!
I am Unix expert not AIX expert. I wonder the 2nd column has PID >99999 - this is quite high. Maybe too high?
