UNIX for Advanced & Expert Users

Hi Friends,
we are using RHEL4.2 (Redhat Enterprise Linux ) .My problems is when
more more than 51st logs in it is not allowing.It allows only 50 users
to log in i.e one user logs-in in 4 to 6 different virtual windows using
f1 to f6 , if I kill the older one sometime the file which the person is
using gets locked and that file may or may not get corrupted.I know from
the command who -u ( the number of users logged in).
The moment 51st try to login it does not allow.I have to reboot the machine
which is time consuming and disrupting the smooth working .

Is there any other solution other then killing of the process ???

Thanks in advance.

What does it actually do? What does it actually say?

What are the contents of your /etc/limits.conf file?
