data for longer retention. Rediscovery NotesWhen hitting this problem, crflogd.log may show the retention size being
suddenly updated to a large size. ------------------------------------------------------------------2014-02-03 15:36:29.799: [ CRFLOGD][2363541248]updateDBRetention: new retention is 1094795585 seconds and 4702111234474983745 bytes------------------------------------------------------------------Current retention value may be checked with following command.
If the retention value (unit: seconds) shows a large value like

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 andchange 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.
