FTPS-690 — Data transfer size limit exceeded
The administrator limited data transfer volume and user has transferred or requested to transfer more bytes than the limit is.
In download cases, the error should be detected prior to data transfer is started (using the SIZE command), for upload, such a prevention is not possible, so the data transfer is stopped when reaching the limit.
In the first case, proxy rejects user request, in the latter one, data transfer is stopped. Session continues.
