restarting xorg by switching to runlevel 3 and back to 5 or even reboot don't change that.
IMO this makes no sense. Maybe we do not understand the output of 'zypper ps' in the Files column. It might have a different meaning than we assume. PID | PPID | UID | Login | Command | Service | Files ------+-------+-----+-------+---------+---------+--------------- 21830 | 21829 | 0 | root | Xorg | | /drm mm object | | | | | | /drm mm object Jan, could you shed a light on this output? What's the meaning? Usually there is no /drm file or directory on our systems. What does "mm" and "object" mean? "mm" maybe "memory mapped"? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

'zypper ps' lists meanwhile deleted open files owned by a process. This per se does not indicate any problem. Those files can be libraries or executables, which may indicate that the package providing the lib/exe was deleted or updated. In that case a service restart might be appropriate, to make sure the updated service is also running. But it may also be the process uses shared memeory or some memory mapped tmp file. We can not tell this appart from a shared library. If people are confused by this, I can add an option to CheckAccessDeleted, so zypper can ask not to collect any name not starting with 'lib' or any file not located in a directory named 'bin'. The full list can always be obtained by calling 'zypp-CheckAccessDeleted'. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Casual, please attach the output of ' 'zypp-CheckAccessDeleted'. BTW, I never heard about Xorg opening a file called '/drm mm object'. This sounds more than weird to me. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This is what zypper will report then. zypp-CheckAccessDeleted will continue to list all access to deleted files. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This could very well be a standard procedure on Unix to pass over a file descriptor to a different process. Something like this. So most likely a false positive ...

Obviously the check needs to be a little bit more picky about what to report, as suggested by Michael in c#5. lib and bin seem to me as good candidates. So all should be as it should now.
