3004-312 All available login sessions are in use.

Hello,

I have a strange situation here.
I am running an AIX6.1 machine and i face a problem when i am trying to login via telnet.
When i use my username and password to login to the server i get the following message:
3004-312 All available login sessions are in use.
The weird thing is that if i try to login through ssh then i login with no problem. I face this problem only when i am trying to login using telnet.
I did some search on the web and everybody mention something about license but i dont think that this is the case. I already checked the server and i have 10000 users license and only 6 users are connected to the server. Also i guess that if the license was the issue then i could not connect using ssh either.

Can anyone help me with this?

Thank you

login as root and issue the following command

smitty chlicense

...check value and increase.

the value there is 10000.
this is not the issue

ok i found the problem
the file /usr/sbin/tsm had wrong access rights.
the access rights of this file must be root.security
