Hi. We seem to be experiencing a very odd issue with Xen 3.0 (RPM
version under CentOS). When establishing a socket (via any application
- for example telnet to a mailserver on port 25) there is an almost
precise 10 second delay before there is any throughput. This only
happens intermittently and appears to occur on all VDSs on the same
system. This does not occur on identical physical systems on the same
network.
dmesg on the host node shows lots of 'xen_net: Memory squeeze in netback driver.' but I'm not convinced this is the cause as they do not correspond with the delays. It's almost as if it's waiting for something to time out... Many thanks in advance for your assistance/thoughts/ideas/input. Regards, Adam Smith. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
