Solutioncouple of suggestions
run the dmesg command to see if there are any recent messages
run glance and look at the process tables (press t at the main screen)
I would look at the nproc parameter, specifically, because it will produce the described system when maxed out.
Look at the syslog for error messages.
Another possible cause is DNS.
verify the nsswitch is configured correctly, /etc/hosts is correct, and the forward and revese lookup work correctly

Re: HP9000 K class
The login process with "telnet" is as follows:
- client connects to TCP port 23
- inetd opens a socket, starts telnetd to handle the connection
- telnetd displays the "login:" prompt and receives the username from the client
- telnetd starts "login" and gives the username as a parameter to it
- "login" displays the "Password:" prompt, receives the password from the client and sends it to the PAM libraries for verification
- if the PAM libraries say the password is correct, login takes up the user's identity and starts the user's shell.
- the user's shell will execute the system-wide and individual login scripts, if they exist. Different shells will use different login script names.
You might be hitting system-wide kernel resource limits, e.g. nproc or nfile limit or simply running critically out of memory. If there is no space to start a new process, the login process will be aborted immediately.
As DCE suggested, run "dmesg" to see if there are any kernel messages that might explain the situation. If there are any messages like "

Re: HP9000 K class
The pid msg I sent must be old since current pid's for active users today are of a completely different range of numbers.
If you could provide commands to view the syslog andhow to handle nproc or nfile we'd be greatful .

Re: HP9000 K class
To check nproc and nfile you can use sar.
# sar -v 5 5
(sar -v
You will get some output like:
# sar -v 5 2
HP-UX hquas08 B.11.00 U 9000/800 06/05/07
11:31:50 text-sz ov proc-sz ov inod-sz ov file-sz ov
11:31:55 N/A N/A 118/276 0 476/476 0 585/920 0
11:32:00 N/A N/A 118/276 0 476/476 0 585/920 0
The proc-sz column is your nproc usage. The 118/276 means that you have 118 processes out of a maximum of 276.
The file-sz column is your nfile usage. The 585/920 means that there are 585 files open and you can go up to 920 open.

Re: HP9000 K class
For my 'sar' commands above, if you require more information have a look at 'man sar' (the sar man page).
By the way, not that this helps you any, glance was available for HP-UX 10.20, but it was, and still is, a product you have to purchase separately.
