    [ https://issues.apache.org/jira/browse/OAK-1494?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13919488#comment-13919488 ] 

Alex Parvulescu commented on OAK-1494:
--------------------------------------

This was initially about the backup, but now I see this error even at init time
I see the requests going through for
 - /j/root
 - /j/root
 - /s/9938b68d-6c70-42b1-a499-2a68710ecab0

and then init fails with the mentioned error.

> I'm experiencing some issues with the http failover: the backup of the http store is throwing some errors.
> The error comes from running the backup a few times on the same directory (much like an incremental backup) and the segment that causes this seems to have a really small length (284 or on a different occasion 388 bytes transferred).
