autossh might help.  It starts ssh sessions and periodically checks them to
make sure that they're still passing data-- if they're not, it terminates
them and starts a new one.  This is often helpful, but maybe not in your
case, since you say that other tunnels are still good after the X tunnels
fail.  I don't know what would cause that.
thanks.  I may try that.  Another data point.  Tunneling sessions using 
putty don't die.  It seems to be only OpenSSH tunnels that have problems.

yes, I am using the -Y option is recommended in the FAQ.  I am using a 
reasonably current (as of last week) copy of openssh via cygwin.
