[Linux-cluster] strange modprobe drops VIP & fails service

[danwest]

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?

Feb  9 13:44:32 node2 modprobe: modprobe: Can't locate module 0
Feb  9 13:44:32 node2 clusvcmgrd: [18150]: <err> service error: IP
address 147.107.188.81 missing
Feb  9 13:44:32 node2 clusvcmgrd: [18150]: <err> service error: 0: error

Feb  9 13:44:32 node2 clusvcmgrd: [18150]: <err> service error: Check

Thanks,
