You have been having node evictions for a few weeks? And have done nothing about it?? If your employer has invested in RAC in order to gain some high availability, he will not be happy. Better start searching on MOS for those various messages, and if you can't find anything, raise a TAR pronto.

LMNn is one of the multiple processes involved in Cache Fusion. If it is having difficulties, there are typically one of two areas of concern, either a slow or improperly functioning Cluster Interconnect or resource starvation (typically CPU).

Cheers,
