While importing building structures in Rostock, Germany, we came across a problem with osmarender sometimes not rendering all buildings, instead it renders lines and triangles. These errors only appear for areas/bboxes with huge changesets.
After using xapi to download some of the buildings myself for editing, josm told me about missing nodes. Comes down to the fact that the xapi query returned not all nodes for some areas.

Example: [http://osmxapi.hypercube.telascience.org/api/0.6/[kvl_hro:type=][bbox=12.160,54.067,12.192,54.078]] and corresponding changeset [http://www.openstreetmap.org/browse/changeset/1211098]
