For the Socket-Related errors seen in the event log on the Reporter, these are communication-related, between the FTP server and the Reporter. This error should be ignored, provided the log processing by the database(s) isn't truncated.
For the fatal error that forced the log source to unload, The reason the log source unloaded was because the remote FTP server terminated the transfer early. Again, if log processing isn't truncated by this, the error should be ignored, as it is triggered by the FTP server and not the Reporter.
Note: we recommend using an external FTP server, in a production environment, for better control and management of the FTP access log transfer to the Reporter.
