/var/log/messages flooded with "unregister_netdevice: waiting for lo to become free"

[Mattias_Jansson]

Logs appear on both members,  23900 VSX/VSLS cluster R81.10 take 174.

Anyone who knows what is causing this and how it can be solved?

Did you recently delete an interface? Was is a VTI interface?

[Mattias_Jansson]

It seems that the messages started after the removal of a virtual server from the vsx-cluster.
No VTI interfaces are used on the cluster.
Policy push on vs0 and cpstop/cpstart on vs0 didn't have any effect. The logs are still repeated.

When did you notice this? Any recent changes?

lo = loopback interface. Normally you will not change something there. Have you tried already the basics? Like turn off / on interface. Policy push to vs0. cpstop;cpstart etc

[the_rock]

Great point Lesley, missed that.
