> Key: AMQ-1479
> URL: https://issues.apache.org/activemq/browse/AMQ-1479
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.0.0
> Reporter: Rob Davies
> Assignee: Rob Davies
> Priority: Blocker
> Fix For: 5.0.0
>
>
> The AMQ Store allocates entries in the data logs for commands (including
> messages/acknowledgements/transaction boundaries etc) - but relies on the
> reference store for keeping track of data files that are being used. Updates
> to the reference store happen at a checkpoint() - asynchronously. The problem
> is that for a fast producer, the current data file (one being written to) can
> move on past the last known data file to the reference store. As the
> cleanup() task is a scheduled task - and not coupled to check points - the
> cleanup task can remove data files that the reference store is not yet aware
> of AND have are previous to the current data file being written too.
> This issue can result in errors from the AMQ Store such as:
> Message: java.io.IOException: Failed to read to journal for: offset =
> 2374, file = 1, size = -1, type = 0. Reason: java.io.IOException: Could
> not locate data file data--1
