Telnet session disconnects abruptly

I have inherited and SCO OpenServer Release 6 server. The clients connect using telnet to get to a proprietary database application for Service tickets. The issue I am currently having is that the connection just stops abruptly and you can see "telnet session terminated" on the terminal emulation software. The terminal emulation software (Attachmate Relections) has a trace function and I can see an received FD_Close from the server. I have tried a wireshark trace as well and can see several TELNET retransmissions before the disconnect. This has happened with two different terminal emulation programs and on different computers on the network. I have checked /usr/adm/messages and there is nothing relating to the telnet sessions, and I have checked /usr/adm/syslog and I only get the following messages

Code:

service bootpd[2175]: IP address not found: xxx.xxx.xxx.xxx

Where xxx.xxx.xxx.xxx shows the IP address of the computer connecting.

Is there anyway to find out why SCO is disconnecting the sessions. There is no rhyme or reason I can see. It can occur after 1 minute or after 1 hour. If I have two terminal emulator session running on the computer at the same time one session is disconnected and the other keeps running fine for the rest of the day.

I've tried the switch but don't see any errors?

Would anyone have any ideas on why SCO appears to be dropping the connection and where I can look?
Thank you
