Exception when pushing to remote

I am getting the following exception when pushing to a running git daemon (with receive-pack enabled). the exception only occurs when the daemon is running on a separate machine, not when I run the deamon on the same machine as I am pushing to.

LibGit2Sharp.LibGit2SharpException: Error receiving socket data: An existing connection was forcibly closed by the remote host.

at LibGit2Sharp.Core.Ensure.HandleError(Int32 result)
at LibGit2Sharp.Core.Proxy.git_push_finish(PushSafeHandle push)
at LibGit2Sharp.Network.Push(Remote remote, IEnumerable1 pushRefSpecs, PushOptions pushOptions, Signature signature, String logMessage) at LibGit2Sharp.Network.Push(Remote remote, String pushRefSpec, PushOptions pushOptions, Signature signature, String logMessage) at LibGit2Sharp.NetworkExtensions.Push(Network network, IEnumerable1 branches, PushOptions pushOptions)

the git daemon is run using this command: git daemon --base-path=. --enable=receive-pack --export-all --verbose

Comienza en Network.Push y en la llamada a git_push_finish mostrada en el stack trace. Reproduce el push contra una máquina separada usando el comando git daemon proporcionado, compáralo con un push en la misma máquina y sigue el rastro hasta determinar dónde cierra la conexión el remoto. Se considera completado cuando el push remoto deja de generar esta excepción y los entornos diferentes quedan cubiertos por una prueba de regresión.
