Timothee Maret commented on SLING-9052:
---------------------------------------
Currently, the code [catches all exceptions raised during
import|https://github.com/apache/sling-org-apache-sling-distribution-journal/blob/697c9dd7ba83c5bf10e6a148aba971db1e8e7832/src/main/java/org/apache/sling/distribution/journal/impl/subscriber/DistributionSubscriber.java#L313-L316],
retries follow an exponential delay (since SLING-10592) and the number of
import attempts is reflected in the json representation of the queue and/or
queue item. One can get the json representation at
/libs/sling/distribution/services/agents/publish/queues.2.json and looking at
the property .<queueName>.<itemId>.attempts (e.g.
76cbf150-d210-4183-9af7-1a311e4e134a-publishSubscriber/package-0@878209/attempts).
[~dsuess] Anything left here ? Can you still reproduce this issue ? If not, I
suggest to resolve this one as `Cannot Reproduce`.

> Components: Content Distribution
> Reporter: Dominik Süß
> Assignee: Christian Schneider
> Priority: Major
> Fix For: Content Distribution Journal Core 0.1.20

>
> During the reproduction attempt of another issue a node was mistakenly
> replicated incomplete (not satisfying the OakConstraints) leading to
> OakConstraint0025 - this should have caused the replication to be considered
> failed as the replicated node couldn't be written into the repository at
> first hand - instead this caused >4000 retries within an hour until being
> noticed.
