Modify BDBSIZE parameter in config file crf<hostname>.ora to 
adequately lower value. To do so, follow these steps:
 
1. Issue "$GI_HOME/bin/crsctl stop res ora.crf -init " on all the nodes of cluster.
2. Locate the config file $GRID_HOME/crf/admin/crf<hostname>.ora
3. Manually edit the crf<hostname>.ora file on every node of the cluster and
   change BDBSIZE tag entry and remove the value (set it to blank) or 
   set it to a desired value, eg. 61511. Do not delete the BDBSIZE tag itself.
4. Restart ora.crf daemon on every node.
