Thank you for the infor. I will check on this.
Good day. Further checking on this. I am sorry we do not know what caused the issue. This might be due to the reason of some incompability in the driver in the previous version. It is recommended to update to latest version.
Thanks for your answer.
Yeah we tried with newer drivers (not the last but the 4.1.2) and the SSH freezes disappeared. However when we did notice that this time, the ixgbe process was often in uninteruptible state (and no more Events).
