SUMMARY: Very strange vmstat issue

Looks like the problem has been resolved. Why this situation exists I
don't know.

Two V480's same OS and presumably the same patch releases. Vmstat is
whacked on one but not the other.

patchadd -p reveals that the patch levels are the same on both machines.
uname -a though reveals that 117350-xx is the kernel patch on one
machine but 108528-29 is what uname -a reveals on the other. patchadd -p
still shows 117350-xx on that buggy V480 but apparently something
happened during the patch install which did not get installed properly.

Anyway, I re-applied the 117350 patch along with the fix patch for
vmstat (117000-05) and the problem has gone away.

This would be the first time in 15 years that a showrev or patchadd
command stated a patch was installed when apparently it was not.

Thanks for the help pointing me to the 117000-05 patch.
