sudo su - takes too long to execute.

[KiddA]

Hi people!
I'm having this weird issue when trying to do "sudo su -" in a 11iv2 HPUX Itanium Server.

The thing is that it takes too long to ask me for password...

Sudo version is 1.6.9p11.

I've also tried "tusc sudo su -" to see if at some point it sleeps... but all I get are lots of lstat:

I'm attaching the tusc output for anyone who are willing to help me :P

Thanks in advance!

At what point while using 'tusc' did you notice the long pause? that would tell you where the problem is.

It is doing several 1 char reads from stdin. Did you forget to type in your password?

If you are going to use tusc, use:
tusc -fp -o tusc.out command ...
