Trouble while uploading files

**bassdaddy777** · May 25th, 2003, 9:48 PM

Hi,

I get this error while using 3D-FTP to load my files. Doesn't happen on other servers.

Quote:

421 Too many connections (3) from this IP    Service not available, closing control connection.

Any suggestions for a work around? Using only 3 threads slows my transfers quite a bit!

Thanks,

Yes, I agree, I am having this problem too due to too many connections. It only happened recently, so I assume that you have just enabled such a restriction.

The problem is, if I have 200 files to upload to my server, using only 3 threads can take me ONE HOUR to complete the upload, as compared to 15 minutes before.

Thus, PLEASE PLEASE REMOVE THIS restriction??? Thank you!!!!!

Threads are individual connections to the FTP server, some FTP clients like SmartFTP allow multiple threads - more than one connection, allowing you to upload several files at one time. For example, if you have 200 files to upload (like php files or html files), doing one at a time (standard ftp client) will take a very long time - not becuase of a slow upload speed, but because of the "handshake" that needs to be done between each individual file - with multiple threads, one thread is uploading, another is handshaking and then uploading, while a third is connecting...

Think of it as when you download more than one file via IE at one time - instead you are uploading.

Thanks N715DP - you explained it better than I would have.

Being able to use multiple threads sure gets things done a lot faster. Since they have it limited to 3 threads they must know what they are and why it is set up that way. If they have it set that way for a good reason I'll live with it but I may pout and grumble quietly to myself.

My guess is that they have it set to 3 to limit the "hammering" on the ftp server(s) as 1 connection x 200 files is a lot less load (CPU and otherwise) than 3 connections x 67 connections. The reason for this is that each time a thread starts (each file upload), the sign on process and handshake take place again and again, where as with a constant connection (1 thread), the sign on happens once and then the handshake happens again and again.

While it's a bit of a pain when doing a ton of files to only be able to do 3 threads, it's better than being able to do, say, 10 threads and have a slow responding server.

But if you look at the cpu usage under CPanel, it hovered around 0.03 - 0.05 most of the time.

I understand the cpu resources taken, but what about raising the limit? Like setting a max of 10 connections instead of 3?
