What makes you think that it's related to
SSH? Does an idle Telnet connection stay up
longer? Is there a TMOUT (or similar) time
limit in the shell on the remote system?

What is the remote system?

Hi,

There may be network timeout limit.

From server site ssh configuration is set in following file.
/opt/ssh/etc/sshd_config

Hi,

Can you send output of /etc/opt/ssh/sshd_config file.

wheather this issue is only with ssh or in telnet also.

if issue has come both telnet and ssh, then look over /etc/profile file for TMOUT veriable value.and also look over user's .profile for TMOUT variable value

Regards
Saurav

First:
echo $TMOUT

Then, if it's set, start looking for who set
it. If it's not set, then I wouldn't bother
looking for where it gets set.
