Latest Fetch downloaded kept on stalling (5 posts)

My Fetch v4.3 has been working, with some quirks, but never stalled as much, as the recent versions I downloaded, the past few days. The main problem with the version 4.3 was that when I edit online -- instead of my usual edit in my computer and then upload -- several new Fetch windows would appear once I click on save. As a result, I have a gazillion of new Fetch windows, if I do several edits. At times, it would then freeze or quit the Fetch application.
There were several notes of latest Fetch version to be downloaded recently, and I am not sure if it was not such a good decision.
Since I upgraded (now to the v5.04, hoping the prior problems would be solved in the latest version), my uploads kept on stalling. I could not upload more than 10 files, sometimes and it would stall again.
At present, I am uploading a very large application with more than 3,200 files (33.8MB) in nested folders (folders within folders). And, it happens so often. What would take me usually about an hour of upload -- would not take the whole day, because of all the stalling and the need to check that I find the appropriate file in a nested folders program.
It attributed it to Firewall, and that it should be turned off. Which I did. But no go. If the passive mode in the Fetch General Preferences is checked, it would suggest, uncheck the latter, when it stalls. So, I do that. Then, when stalls again, it will suggest, check passive mode.
Any ideas on what is causing the stalling?
It is driving me crazy... I hope you could help.

It is not uncommon for FTP transfers of large numbers of files to fail because of network timing issues. Fetch 5 tries to recover from many failures, but there are some failures that can't be recovered from.
My first suggestion would be to find out if your server supports SFTP. If it does you are likely to have better results with that protocol.
If SFTP is not an option I would recommend trying a number of different FTP clients, to see if any are more reliable. I would be interested in hearing your conclusions if you try this.
I would be happy to look further into the specific reason why Fetch is stalling. That will require collecting some more information about the failures. Let me know if you would like to proceed in that direction.
I decided to just play with the various possible combinations between the preferences of Fetch and the MacOSX Preferences.
More specifically whether PASV in Fetch is checked or unchecked;
Fetch General Preferences:
Use passive mode transfer (PASV)
In relation to that of System Network Preferences. After several "trial and errors", what seems to work (knock on wood) eventually was for the PASV to be unchecked and the firewall off.
With this, I was able to upload a complete copy of the tikiwiki (33MB) with more than 3200 files without any interruption -- as I had been getting in the past (before I downloaded the latest versions)
I will know more during the next few weeks, if the uninterrupted transfer will be stable. And I will keep you updated.
My only concern is that I have to have the Firewall "OFF". I thought this is one of the security features of the Mac that makes it less vulnerable to attack?

I'm not aware of any specific threats that are blocked by the OS X firewall, but in theory yes, you are more vulnerable with the firewall off. So you may want to turn it back on when you aren't transferring files.
I will take your advice.
