[opensuse] pmap - "failed to parse"

Hello,

on my system kernel (3.0.26) I try to determine memory resources of
processes with pmap. But I get the error:

===================================
~# pmap 3020
failed to parse /proc/3020/smaps
===================================

(pid 3020 is for example the crond)



The file /proc/3020/smaps is readable and looks like this:

If I start pmap with strace, the file is open and it reads 2 time 1024
bytes, then it ends.

On a similar System with kernel 2.6.32 pmap works.

The version from pmap is in both cases the same:

~ # pmap -V
procps version 3.2.7


Does anyone can help me. procps should work with kernel 3.x..

Thanks Meike
