truss command on 5.2.1-p9

[Murat Ustuntas]

Hello all,

I need to truss command on FreeBSD 5.2.1-p9. But, if
I want to run the command truss says me:
    # truss /usr/sbin/sshd
    truss: cannot open /proc/8668/mem: No such file or directory
    truss: cannot open /proc/curproc/mem: No such file or directory

sshd process is running, and in the proc directory,
i have the number 8668 and mem too. What is the problem? How
can I fix that? (I dont know that this is a bug or not :( )

Regards,

Murat
