Re: [Condor-users] can I run mixed versions of condor together?

[Steven Timm <timm@xxxxxxxx>]

It depends on if you are using TCP sockets for anything.  The
tcp socket negotiation was considerably improved in the 7.2 series.
In the mid 7.0 series there were certain bugs in which a
dance of death could be set up between the schedd and startd or
schedd and collector.  I would upgrade everything if I were you.
There have been a lot of memory leaks fixed in collector and negotiatior
since 7.0.1 too.  Also if you are doing GSI authentication in
your condor pool, which you should be doing if you are on the OSG,
 it's vital to get up to the new version.
