Futher investigations: I have disabled rx and tx checksumming offloading and proceeded two cycles of verifying process - no problems at all. The only problem is that CPU usage is increased a lot. ethtool --offloading eth1 rx off tx off and ethtool --offloading eth3 rx off tx off on both nodes May be this is a just coincidence and server just wasn't under heavy load but if not what can I do then?
