GET /pattern-*/_mapping/field/* kills the server

Server immediately becomes irresponsive, java process rss size hits the roof and after some time this starts showing up in the log:

[2015-05-07 05:06:11,806][DEBUG][action.admin.indices.mapping.get] [Soldier X] failed to execute [org.elasticsearch.action.admin.indices.mapping.get.GetFieldMappingsIndexRequest@3844bde7]
