site to site transfer stops after file complete, even if non-empty queue

[bionic]

Hi ;)

after transferring a file by site to site transfer, FFXP stops transferring next files in queue after every file transferred complete. The next file in queue doesn´t start transferring. In the status window:

[R] 226 Transfer complete. 15000000 bytes in 337 sec. (44.51 Kb/s).

The "remaining time" is ???? and "elapsed time" is still rising (although the status window shows "..transfer complete.."). After few minutes, FFXP loses connection to one of the servers.
The "critical" server can do passive mode without probs, firewall seems to be configured right (i know the admin). I also tried alternative site to site method (PASV and/or NOT PASV), but same problem..
The problem is since the admin changed his ISP from Telecom ADSL to cable-munich..but the ISP shouldn´t be the problem?!?

I tried 2 different versions of FFXP (3.0 and 2.0) on two computers

Status window:
[10:22:44] 227 Entering Passive Mode (83,243,117,xxxxx)
[10:22:44] PORT 83,243,117,xxxxx
[10:22:45] 200 Port command ok.
[10:22:45] STOR xxxxxx.rar
[10:22:45] 150 Opening BINARY data connection for /uploads/xxxxxx.rar
[10:22:45] RETR xxxxxx.rar
[10:22:45] 150 Sending /Mp3s/xxxxxx.rar (15000000 bytes). Mode STREAM Type BINARY
[10:28:04] 226 Transfer finished successfully. Data connection closed.

..and this is the point where the queue stops being transfered, the "remaining time" is ???? and "elapsed time" is still rising.
On other servers it works fine..looks like this:
[10:22:44] 227 Entering Passive Mode (83,243,117,xxxxx)
[10:22:44] PORT 83,243,117,xxxxx

during FXP when transfer is done you should see 2 'transfer complete' messages. but your log shows only 1, which means connection to the other server was lost.
either your firewall or server's closed that idle connection.
try enabling 'send noop during transfer' and/or change idle connection timeout value in your firewall.

also please update your message board profile to include your FlashFXP ID.
