check the process table to see if shells for those ttys are still
open.

e.g.

[aphro@portal:~]$ w
 20:00:16 up 9 days,  1:31,  2 users,  load average: 1.38, 0.69, 0.60
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU  WHAT
aphro    pts/3    aphro.aphroland. Tue19    0.00s  0.32s  0.09s  w
aphro    pts/4    aphro.aphroland. Thu22   21:44m  0.08s  0.05s  bash
[aphro@portal:~]$ ps auxw | grep 'pts/4'
aphro     8978  0.0  0.1  4048 1660 pts/4    S    Nov07   0:00 -bash
root      8988  0.0  0.1  4048 1644 pts/4    S    Nov07   0:00 bash
aphro     2624  0.0  0.0  1336  468 pts/3    S    20:00   0:00 grep pts/4

then kill the process ids. I have found when killing dead sessions
only kill -9 to the shell seems to work(at least with bash).

if there are no processes then your log files may have a bit of
curroption in them(I haven't had this happen in years), I am not
certain how to deal with it(perhaps rename/remove them?)
