Gary Tully created AMQ-6625: ------------------------------- Summary: IOException in kahaDB needs to pause pending IOExceptionHandler intervention Key: AMQ-6625 URL: https://issues.apache.org/jira/browse/AMQ-6625 Project: ActiveMQ Issue Type: Bug Components: KahaDB Affects Versions: 5.14.0 Reporter: Gary Tully Assignee: Gary Tully Fix For: 5.15.0
KahaDB can recover from kill -9 by replaying the journal from the last checkpoint or by detecting and reapplying partial writes to the index. However this activity is compromised if the journal or index accepts subsequent writes. It an lead to skipped write batches or skipped partial updates to the index. The desirable behaviour of treating an IOException as fatal and stopping the broker in the knowledge that it will restart and fully recover needs to treat the first IO error as fatal and by default not accept any further writes. A more advanced IOException handler can facilitate staying alive in more specific scenarios and reactivate kahadb. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
