This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF."

Esto solo ocurre cuando cache_peer es usado con la funcionalidad cache digest. El problema se presenta porque el bloqueo en vivo de peerDigestHandleReply() en el archivo peer_digest.cc maneja inapropiadamente EOF."
