What version of netback are you running? The one from the 3.0.3 release is known to have a bug which would cause high-bandwidth transfers to stall. The offending function is netback.c:tx_add_credit(). You should be able to take the version from xen-unstable and copy it into whatever version of netback.c you are using. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
