Islandora related Fedora log errors

[Serhiy Polyakov]

Hello,

I installed Book SP (clean Islandora 11.3.1) and ingested one object
into the collection. I am getting two types of errors repeating
numerous times in fedora.log during browsing the object even browsing
goes alright on the Drupal side. I had these in previous versions of
Islandora.

Should I ignore the errors or try to find the reason?

Thanks,
Serhiy

ERROR 2012-01-23 23:39:28.025 [http-8080-5]
(FedoraAPIABindingSOAPHTTPImpl) Error getting datastream dissemination
org.fcrepo.server.errors.DatastreamNotFoundException: [DefaulAccess]
No datastream could be returned. Either there is no datastream for the
digital object "islandora:root" with datastream ID of "QUERY " OR
there are no datastreams that match the specified date/time value of
"null " .
…
==========Excerpt =======

Instead of “islandora:root” other errors include
“islandora:bookCollection” or “islandora:44” (my book object)

Instead of "QUERY " other errors include "POLICY "

Something to note in the error below is that localhost is used in
request to JP2 stream unlike in other requests. Although, immediately
after the error the same request goes alright. This errors happens
when I "read" book pages even reading goes alright.

You can safely ignore these errors - they come from Islandora checking to see if certain option datastreams exist, before falling back to default methods.

I see about error (1) described in the message. I will ignore those.

Error (2) is of different nature and comes when JP2 request is issued.
But not every time as end of the error shows. It also causes error in
Tomcat’s localhost.log

Thanks,
