LollipopにてVolleyのリクエスト(GET or POST)を実行した際に 極稀に瞬時にErrorListenerがコールされてしまいます。

Lollipopのバージョンは5.0.0および5.0.1どちらでも発生します。 （体感的には5.0.1は頻度が減ったようにも感じますが再現はしています） 機種はNexus4, Nexus5, Nexus7 2012です。

VolleyErrorの内容を見るとstatusCodeはなしで 例外内容はInterruptedIOExceptionとなっていました。

どうやらスレッド関連で発生しているようなのですが根本原因が分かりません。 同事象が発生している方、対応された方、ご教示をお願い致します。

【追記】 以下にVolleyのデバッグログを添付致します。
