[Gluster-users] Geo-Replication just won't go past 1TB - half the replication process crashing?

Thu Sep 5 18:01:33 UTC 2013

No rsync process is running.  I tested for it several times over 10 seconds.

Here's the trace on feedback.  I put it on TinyPaste instead of in
everyone's inbox out of courtesy:  http://tny.cz/505b09c8

Thanks,
Tony
