Comment 18 for bug 1401879

The bug is reproduced on 6.0.1 staging job:
http://jenkins-product.srt.mirantis.net:8080/job/6.0.1.staging.centos.bvt_1/49/

Also, this time there was functional impact of DBDeadlock - it caused InternalServerError on network deletion request and that in turn caused OSTF tests failure.
