[jira] [Created] (MAILBOX-322) Diagnose ghost mailbox

Tellier Benoit created MAILBOX-322:
--------------------------------------

             Summary: 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.
