Hi

I use SecureBlackbox FTP server in c#. I test FTP server by filezilla(FTP Client) in below Step.

1.Add file to download queue.
2.Click "process Queue" to start download.
3.Click "process Queue" again to stop download.

FTP Server will hung up now , OnTransferProgress event continues to fire continuously. The CPU usage up to 30% ~ 40%.

How to pass this type event, and still get other client download request ?

Hi Peter,

Thank you for contacting us.

To speed up the investigation, could you please specify if you are using TElFTPSServer or TElSimpleFTPSServer component and whether the issue is reproducible with the sample application?

Ken

Hi Ken

It's TElSimpleFTPSServer component and the issue is reproducible with the sample application (Samples\C#\FTPSBlackbox\Desktop\Server).

Hi

We've faced serious situation which caused by this issue. It's been found from our ongoing project for an important client. And this issue now apparently will strongly impact project acceptance for project close meeting which scheduled around Jan 25th, 2 weeks later from now.

As under pressure of that, we'd like to ask if there is any chance new fixed version could be released before 25th for us to completely fix this client issue? we sincerely appreciate your effort.

Looking forward to hearing from you soon.

Hello.

I've already sent you pre-compiled assemblies via Helpdesk on the 4th of December. Did you check them?
