Repair Failing due to bad network

[David Koblas]

I'm trying to bring up a new Datacenter - while I probably could have 
brought things up in another way I've now got a DC that has a ready 
Cassandra with keys allocated.  The problem is that I cannot get a 
repair to complete due since it appears that some part of my network 
decides to restart all connections twice a day (6am and 2pm - ok 5 
minutes before).

So when I start a repair job, it usually get's a ways into things before 
one of the nodes goes DOWN, then back up.  What I don't see is the 
repair restarting, it just stops.

Is there a workaround for this case, or is there something else I could 
be doing?
