XS7.2 patch XS72E015 igb bond flapping problem

Hi there!

We have very often on XS7.2 (applied patch XS72E015) - igb bond flapping problem.

Problem occurs time to time - and it is impossible to reproduce right now.

We have this problem almost daily...

What happens?

One of the network drivers hangs and will not work anymore (sometime flaps UP/DOWN) - until modprobe -r igb and modprobe igb back - after that is everything working again - also server reboot helps

[root@xen ~]# ethtool -i eth0

Now is the latest version 5.3.5.15 12-19-2017

-> but question if it will help...

Without bond it crashes very very rarely.
