For each node stop crf service:  

>crsctl stop res ora.crf -init

  For each node edit crf.ora file  

> vi $GRID_HOME/crf/admin/crf.ora

#old value. unit: seconds

BDBSIZE=1094795585

#new value: approx 1 year
BDBSIZE=31536000 

For each node: Delete *.bdb files:

> cd $GRID_HOME/crf/db/
> rm -rf *.bdb

For each node start crf again

>crsctl start res ora.crf -init
