Antoine Duprat resolved MAILBOX-322.
    Resolution: Fixed


> Diagnose ghost mailbox
> ----------------------
>                 Key: MAILBOX-322
>                 URL: https://issues.apache.org/jira/browse/MAILBOX-322
>             Project: James Mailbox
>          Issue Type: Bug
>          Components: cassandra
>    Affects Versions: master
>            Reporter: Tellier Benoit
> Ghost mailbox bug definition:
> At Linagora, for unknown reasons, once in a while, mailbox path based mailbox read misses
for existing mailboxes. For JMAP system mailboxes, provisioning will re-create and overrides
these mailboxes as well, leading to disappearing content.
> We observed this behaviour in our production system, however, we did not succeed to reproduce
it yet, nor have strong certitudes on the origin.
> We need tools for auditing that production system.
> A dedicated structured logger can be added. It will report all mailbox operation (create,
delete, rename and read) as well as missed reads. That will allow diagnosing "ghost mailboxes"
as well as review the patterns leading to it.
