Issue/Introduction

The data aggregator is running out of space.  Upon further investigation we have found that the /opt/IMDataAggregator/data/broker/kahadb is using all the space

Cause

Possible corrupt file preventing cleanup

Environment

CAPM 3.x

Resolution

To resolve do the following:

  1. mv /opt/IMDataAggregator/data/broker/kahadb to /opt/IMDataAggregator/data/broker/kahadb.orig
  2. Restart activemq service
    • Redhat 7: systemctl stop activemq / systemctl start activemq / systemctl status activemq
    • Redhat 6: service dadaemon stop / service dadaemon start / service dadaemon status
  3. The kahadb will be recreated on startup
  4. After confirming the activemq process is running  (see step #2), the kahadb directory can be removed with the following command: rm -rf kahadb.orig from the /opt/IMDataAggregator/data/broker/ directory
You should now have your space back
