Time out related log in libvirtd_source log
So apparently the hosts are quite loaded and so is the network. Either the network is so loaded that the packets just don't come to the destination libvirtd and back in time or libvirtd is not able to accept the connection in time. Could you please capture the TCP connection attempts on both hosts and attach the pcap files and corresponding debug logs from libvirtd from both hosts? Created attachment 1420615 [details]

Hi, Jiri I sent an email to you for more libvirtd logs on env, I'll try to capture the TCP connection attempts on both hosts and attach the pcap files later, thank you! Regards, chhu We're still waiting for the pcap files. Anyway, this seems to be pretty similar to bug 1614182, where some packets were delayed a lot. If it's the packet which is initiating a new connection, the connection times out. *** This bug has been marked as a duplicate of bug 1614182 *** |
