ORA-16014: log 1 sequence# 40845 not archived, no available destinations

Question

Hi,
My RMAN archive script gives the following error. I'm not sure why - there is still about 16 GB diskspace and an archivelog is not more than 50 MB. Does anyone know what could be the cause of this error? Thanks.
