Are you running IPFilter firewall? If so, check that "keep alive"
options are set up properly, incoming and outgoing.

I have a similar problem but in my case it is definetly the ADSL modem
that breaks the connection after about 5 minutes of inactivity.
The first I did was to run a script printing the date every few seconds
or prstat or top running whenever I was idle, but it's a pain.
Then I found the following options on the Solaris 10 sshd server (does
not seem to work on Solaris 9)

In sshd_config:

KeepAlive yes
ClientAliveInterval 250

The interval of 250 is just enough to keep my ssh connections alive.
