yes.  there are a few bugs in the session handling code in 6.4.7.  however,
it is disabled by default in 6.4.X.

most of those bugs have been fixed in 6.6.0, and a couple more in 6.6.1.  the
problem is that 6.6.X will request to have sessions enabled by default.  so
when it talks to a 6.4.7 daemon, you may expose those bugs.

for maximum backwards compatibility, your best bet is to tell 6.6.X not to use
sessions by default.  to do so, add this line to your condor_config file:


then your 6.4.X and 6.6.X pools should play nicely together.  however, the 
downside is that you cannot use any strong authentication or crypto since that
requires sessions.
