"uptime: /dev/ttys003: No such file or directory"

1. I want to make a note on how I work around this issue

2. machine info
tj-yangs-imac:~ tj_yang$ uname -a
Darwin tj-yangs-imac.local 10.4.0 Darwin Kernel Version 10.4.0: Fri Apr 23 18:28:53 PDT 2010; root:xnu-1504.7.4~1/RELEASE_I386 i386

3. I was getting "uptime: /dev/ttys003: No such file or directory" in "Terminal".

Last login: Tue Jun 22 23:22:37 on ttys000
tj-yangs-imac:~ tj_yang$ ls -l /dev/ttys00?
crw--w---- 1 tj_yang tty 16, 0 Jun 22 23:23 /dev/ttys000
tj-yangs-imac:~ tj_yang$ uptime
uptime: /dev/ttys003: No such file or directory
23:23 up 3 days, 13:41, 2 users, load averages: 0.01 0.06 0.10
tj-yangs-imac:~ tj_yang$ date

4. Can anyone confirm above finding in 10.6.4 ?

5. Work around
5.1 Control+N to open 3 new Terminal sessions.
5.2 do "ls -l /dev/ttys003" got created.
5.3 do uptime command and see no more error message.

So why uptime has to lock in on /dev/ttys003 and can't use what ever session it is in ?
