Kernel, and


SLES10 SP1 with kernel, or 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.


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