Our diagnostics and error logs are filling up with errors pertaining to a single account that logs in every half-hour to poll for files. I can confirm that they are successfully getting logged in and can transfer files to/from without error. We do NOT have any Process Triggers configured.
The error message is:
Default Site:user?:<ip address removed>] Error firing OnUpload trigger EnterpriseDT.Net.FtpServer.Trigger.AuditTrigger NullReferenceException: Object reference not set to an instance of an object.
