> SOLR-5354 added unmarshalling of distributed sort field values in {{QueryComponent.mergeIds()}}, but incorrectly performs this (unmarshalling all docs' sort field values) for every doc, and stores the result with each doc. This is unnecessary, inefficient, and extremely wasteful of memory.
> In an offline conversation, [~alexey] described the issue to me and located the likely problem, and [~hossman_lucene@fucit.org] located the problem code via inspection.
> This bug is very likely the problem described on the solr-user mailing list here: [SolrCloud constantly crashes after upgrading to Solr 4.7|http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201403.mbox/%3c83f549bdf8deecbc7567c324ee0cb91f@cluster38.e-active.nl%3e]
