Problem

You or your monitoring system notice a couple of so-called “zombie-processes” in the process list of your UCS domain controller.

root@dc:~# ps aux | grep Z
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root      9383  0.0  0.0      0     0 ?        Z    12:45   0:00 [xmlsec1] <defunct>
root      9384  0.0  0.0      0     0 ?        Z    12:45   0:00 [xmlsec1] <defunct>
root     19222  0.0  0.0  12784   976 pts/0    S+   14:14   0:00 grep Z

Environment

Affected are UCS 4.x hosts with SSO configured. Zombie processes arise when a parent process ends and did not ask his child for the data it requested initially.

Solution

You can safely ignore these processes. They will be cleaned up by the library at a later stage.
With a new release of UCS there might be an update to this issue.
