Has anyone every seen something like this? A modprobe with either a "module 0" or a blank "module " is always followed by the interface loosing its VIP and thus initiating a service failure. All non essential system services were turned off. Not sure what is calling/causing the strange modprobe. Logs are clean, no other events leading up to this. I am now wondering if it could be the cluster itself?
