Do you test it with the same command all the time?<br>
<br>
Have you tried other commands?<br>
Can you do a user/group/host add?<br>

Just noise while we fork off and run another process, in this case keyctl to store the session cookie in the kernel keyring.
So running with strace doesn't result in the session logging out?
