thanks to all people
but, unfortunately, i have to reboot
it seems that my english is very bad, because many guys suggest me that 
there are troubles with nfs or automount, but how can you explain that 
others users continue to login on this machine without any trouble?
c. hoogendyk suggested to look after sunray session, but it's not the 
solution (no session remain)
Before this problem happened, userA can login without any trouble. But 
two days ago, he had problems with firefox or thuderbird, and a sysadmin 
tried to kill all user's processes. And that's why i got a strange 
situation, with zombies processes, and userA unable to login again.
And after one day search without success, it's time to reboot
