-------------------------------
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.
