Consistently seeing the problem with SLED10 SP1 on x86_64.  

With SLES9 SP4 on x86_64 I don't see the problem ever.

So there is a pid 0 in proc?

but if i do an ls /proc/0 it's not there, or an ls -la /proc

> ls /proc/0
/bin/ls: /proc/0: No such file or directory

So this appears to be a SLED/SLES10 issue?

I can reproduce this on both on my desktop and on a SGI Altix 450, the key 
seems to be just do a ls /proc?
