since upgrading to lion ssh connections constantly drop with:
Write failed: Broken pipe
this did not happen in snow leopard, nor does it happen on win7 pro in parralels
apple terminal, zoc, and securecrt all experience the same thing
did apple change an idle timeout setting or something?
MacBook Pro, Mac OS X (10.7)
The changes mentioned towards the bottom of this page by subq seem to have fixed this issue for me:

12 hours+ and the issue has not resurfaced. However, making these changes to your user's ssh config under your own account are more preferable due to future updates overwriting them if made in /private/etc/ssh_config.
After 1 day of testing I no longer experience this problem to such an obvious extent (so far it actually seems like it's fixed altogether). The net.inet.tcp.keepidle and net.inet.tcp.keepintvl variables were modified in /etc/sysctl.conf. Their values were extremely low. I don't know how this happened. The solution was to set these values to their default values net.inet.tcp.keepidle=7200000 and net.inet.tcp.keepintvl=75000 using the "sudo sysctl -w" command.
Firefox + fire ssh plugin
This issue is unrelated to wifi. I turned my wifi off and have been hooked up via ethernet and I still am seeing broken pipes when my sessions go idle for just 10 minutes.
This Write failed: Broken pipe thing is driving me nuts. As I ssh into the linux server to to all of my work, whenever I try to display something a little bit graphics intensive, the ssh session become unresponsive and drop with the given error.
Would it be a problem with X11.app ? I have tried various version of OpenSSH (5.3 - 5.82p) but they're all the same
I know this isn't particularly helpful but I'm another one with this issue. I practically live in SSH on my Mac and this is a real dealbreaker for me, I'm about to try the plist fix that someone mentioned above. Hopefully I'll have success here!
I have the same problems - dropped scp file transfers with a broken pipe on a MacBook with MacOsX 10.7.2. Setting the Server/Client-Timeouts didn't help. The proposed solution with syslogd doesn't work. There is no indication in the scp -v log either. Any ideas are welcome!
I got same issue with my MacBook Pro but Mountain Lion, My iMac, My Mac Mini, My Mac Pro (mac pro is at my studio and iMac is my home office) I have gone to 10 different locations and on all 12 of my linux servers i got same issues, unless i am on my FreeSWITCH system and in CLI that will remain connected for days on end... 3-10 minutes at bash and i lose connection.
I have pretty much the same problem. On my Power Mac running Mountain Lion, an ssh connection to a remote computer with Terminal gives the error 'Write failed: Broken pipe" after a few minutes. However on my Power Book running Tiger on the same local network, there is no problem at all. Apple needs to address this and several other problems.
I suspect this occurs when the remote-connected machine goes on stand-by, without checking if a ssh connection does exist. This is clearly a bug appeared in the few latest releases of Mac OS. REALLY annoying...
No, just run that from your terminal. Let me know how it works out. I have fixed a whole lot of my broken pipes with this. It still isn't perfect, but I can use my systems now... Hope this helps.

What program is running though ssh? rsync? scp?
just terminal via ssh, not running any particular command like rsync or scp
I have the same problem!!!
Write failed: Broken pipe
I have the same issue. Using Real VNC viewer I got the error too.
Could still be DHCP lease expirations and new IP addresses being assigned that would break a TCP connection.
