problema con barman y rsync

Buen día, por favor si me pueden dar una mano para detectar el problema,
tengo un barman haciendo backup de varios servidores postgres.
Funciona bien con 3 servidores, hay un 4to server postgres que no estoy
pudiendo hacer el base backup (barman backup nombre_server) ya que rsync
está reportando un error.
El tema es que si puede copiar archivos pero no todos. Y la transferencia
de los WAL se hace sin problemas.
*A continuación les mando parte del log de barman:*

Cabe aclarar que ambos servidores están en el mismo hardware en dos
maquinas virtuales diferentes, con una red que "vuela" en velocidad.
Postgres 9.2 - Barman 2.10

Desde ya muchas gracias por la ayuda que me puedan brindar.
