Hi Shawn, We committed a fix today which might have fixed your problem, can you check with the latest source?
I tried with two instances of rsync but the problem did not reproduce. If you still see the problem can you give more detailed steps to reproduce the problem? Thanks Krishna On 4/4/07, Shawn Northart <[EMAIL PROTECTED]> wrote:
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,
