Another session logged in but running no processes?


Hi all,

Since I can't figure what's going on, any hint would be appreciated.

My University gives us access to a Linux server, named stud1.

Code:
me@stud1:~$ uname -a
Linux stud1.some.univ.ac 2.6.9-89.31.1.ELsmp #1 SMP Mon Oct 4 21:41:59 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
Apparently I was logged in, and never logged out sometime:
Code:
me@stud1:~$ who
<snip>
me       pts/37       Jan 30 13:27 (6.6.66.66)
<snip>
me       pts/58       Dec 30 19:13
but when trying to find out why I'm still logged in, I can't find it:
Code:
me@stud1:~$ ps faux |grep me
root  30030  0.0  0.0 51128 4360 ?        Ss   13:27   0:00  \_ sshd: me [priv]
me    30033  0.0  0.0 51132 2336 ?        S    13:27   0:00      \_ sshd: me@pts/37
me    30034  0.0  0.0 59684 1536 pts/37   Ss   13:27   0:00          \_ -bash
me    31241  0.0  0.0 10732 1248 pts/37   R+   13:45   0:00              \_ ps faux
me    31242  0.0  0.0 51084  584 pts/37   S+   13:45   0:00              \_ grep --color=auto me
My question is: what is going on? how can I logout this unused session?

Thanks in advance.

Can you kill the bash terminal associated with it?
the o/p of lsof |grep me might also be interesting
