All FxP transfers marked as failed

Never had this with the previous released version but all FxP transfers are marked as failed, even though they are successful.

It also appears to wait about ten minutes after a transfer completing before commencing the next transfer. I didn't see this with the released version.

Post timestamped session log.

Here is a log from testing a single file. I have also been testing with much smaller files (<30MB) and can't seem to get it to report a failure.

What version/build of FlashFXP are you using?

It would appear that the site on the left didn't return a transfer successful reply and FlashFXP is waiting for this reply, while waiting for this reply the site on the right timed out.

I am not sure why this would in turn mark all your files as failed, it could be due to your configuration or an unexpected issue in FlashFXP.

This is something I will need to troubleshoot... However it is very difficult to simulate and reproduce these types of problems effectively under a controlled environment.

hi, 4.3.0 build 1907.

All I know for sure is that this was working fine under 4.2.5 build 1813 (I had about 30 similar sized files and updated to the RC about half way through doing them). The FTP servers at both ends have not changed either.

It does appear to be working fine with smaller sized files though.

You might try changing the

"Enable TCP/IP keep alives" setting in FlashFXP.

Check the setting and set the interval to 2 minutes.

In v4.2 this was set to 2min and in v4.3 it was increased to 2 hours to ensure better compatibility, however some people benefit/require a value as low as a 2min interval.

Brilliant, I changed this to 2 minutes then tried transferring one of the 1GB files across and it was successful!

Many thanks for your help.
