/proc has a directory for PID 0 (/proc/0), but this directory is not accessible at all

This document (3649220) is provided subject to the disclaimer at the end of this document.

Environment

Novell SUSE Linux Enterprise Server 10 Service Pack 1
Novell SUSE Linux Enterprise Desktop 10 Service Pack 1

Kernel 2.6.16.53-0.16, 2.6.16.54-0.2.3 and 2.6.16.54-0.2.5

Situation

SLES10 SP1 with kernel 2.6.16.53-0.16, 2.6.16.54-0.2.3 or 2.6.16.54-0.2.5 will show /proc/0. It is only visible when running
ls /proc
(without any further parameters to ls). Other commands, such as
ls /proc/0
ls -l /proc
stat /proc/0
will all return an error:
/proc/0: No such file or directory

In most environments this is a purely cosmetic issue and can be ignored. However, there are at least two programs (net-snmp and Unicenter) known to run into issues because of this.

Resolution

This issue has been fixed with the maintenance kernel update to version 2.6.16.54-0.2.8, released on the 3rd of July 2008.
