Uploads of 300kb files failing

[thoul]

I'm having trouble uploading files that are approximately 300KB in size. I've tried with FileZilla 3.0.0 and 3.0.1. A 350,555 byte file stops uploading with a server disconnect after 37%. After disconnecting, FileZilla usually won't reconnect, but when it does the same issue repeats and the upload fails again at the exact same point.

Smaller files upload fine and the ~300 k files upload fine when using FileZilla 2.2.25.

The attached log shows an attempted upload which failed, a few automatic reconnection attempts which failed, and finally a successful reconnect with the upload failing again.

Operating system is WinXP Media Center w/ Service Pack 2.

Appears to be a router and/or firewall issue.

Try disabling all firewalls and make sure you're using the latest firmware for your router. Especially make sure things like "protocol fixups" and such are disabled in your router, they do more harm than benefit.

I don't have a router - I use a dial up connection.

I have disabled my firewall (Comodo Firewall Pro 2.4.18.184) and received the same results. Filezilla 2 uploads the files properly with and without the firewall. So, the firewall isn't an issue.

According to the log there's definitely something wrong. Could also be a firewall or router on the server side.

I've been able to switch from using FTP to SFTP and now the files upload correctly.
