sorry, forgot that one. the command used was: rsync -av --stats --progress --delete
i haven't tried setting a bwlimit yet and i'd prefer not to have to if possible. i've got roughly 450GB of data i want to sync over and the faster i can do it, the better. i will try it just to see if it makes things any better. the network is all copper gig with both interfaces trunked and vlan'd (on both client and server). a couple of other things that just came to mind are that i didn't see this exact behavior during the initial rsync. i have three directories i'm trying to sync and when run concurrently, i would see the problem. when run one at a time, the sync would seem to complete without incident. the only difference in the command i ran was that i omitted the --delete flag. ~Shawn On Tue, 2007-04-03 at 11:07 +0530, Krishna Srinivas wrote: > Hi Shawn, > > Can you give us the
