ruby-on-rails - PostgreSQL SSL エラー

Question

Ember.js、Rails、unicorn、PostgreSQL を組み合わせた WebApp があり、それらはすべて Heroku 上にあります。

時々PGErrorが発生することを除いて、すべてがうまくいっています

PG::ConnectionBad: PQconsumeInput() SSL エラー: BN lib

ほとんどの場合、問題なくアプリを使用し続けることができますが、このエラーによって JS が壊れて、WebApp を使用できるようにするためにページをリロードする必要がある場合があります。

Unicorn が PG 接続を失ったようなものであると考えられますが、このエラー メッセージに関連する Web 上の情報はほとんどありません。

任意のアイデアをいただければ幸いです。
