For the last 36 hours, our SPPS system refuses to display discussions, giving the error message "Erro ao transferir os debates do servidor gdoc: Ocorreu um erro não especificado."

It continues to be possible to insert discussions, but not to view them once inserted. New discussions appear in the subscriptions lists, clicking on those items opens the related document but does not show the discussion text.

I have restarted the server, with no change to this problem. There are no unusual error messages in the event log, compared with one week ago. I have also tried restarting only the IIS Admin service, without positive results.

Most of the added value derived from our SPPS implementation arises through the use of discussions to document actions taken, so it is urgent for us to resolve this problem.
