[Halvdan Grelland <halvdanhg@xxxxxxxxx>]

Ok, so I've looked further into this. The only issue I am able to
consistently reproduce happens only in the GML import process. The stack
trace can be found here
<https://gist.github.com/grelland/45acadfbe475422889ec>
Note that this might be unrelated to the looping/recursion issue.,

This does not happen if I pre-stage the meta data payload (ie write it to a
file and import using the metadata importer). My suspicion that the
conflict occurs because of the clear/re-add of attributevalues in the
orgunit.mergeWith() method (which I'm using to merge geodata updates into
the orgunit), which happens within a transactional scope. I'm gonna have to
experiment further to find a solution. Any suggestions are much appreciated.
