Hello Everyone, One of our servers is showing a strange issue, let me paste the output Code: root # uptime 4:37pm 3 users, load average: 0.00, 0.04, 0.04 Its been running since months but you can see after time there isn't any output like up 191 days(s). Even the who command with b and r option isn't giving any output. Code: root # who -b root # root # who -r root # the date command displays correct output. I am not sure but is it because someone has played with utmpx and wtmpx files, is reboot the only solution we have. Can anyone help us since we don't intend to reboot the server for such a reason and also no one has complained till yet.
