su - doesn't work on my solaris 10 system

Hello,

My session hangs repeatedly while running "su -"or "su - user" command. I checked the pam.conf and it's the same as on other server, I checked for nfs quotas in /etc/profile and there are none. Below I send a truss output (last n lines report error but I'm not sure how to read that). Could you please help?
