Gary Tully commented on AMQ-6625:
---------------------------------
The DefaultIOExceptionHandler implements a resume call on kahadb that allows
the stopStartConnectors behaviour or ignore all errors behaviour to be chosen
if necessary.
> 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.
