Bug in ASA OS 7.0.64 for ip inspect and FTP?

Hello,

I have a frustrating problem with FTP across our ASA 5500 using OS 7.0.64.

When an internal user connects in active mode to an external ftp server and starts to download a large file, two connections are opened: one to port 21 of the FTP server and one to port 20 of the same server. During file transfer I can see that the byte count for connection to port 20 is increasing while byte count for connection to port 21 is not increasing and the idle time is growing. I believe this is a mistake and maybe a bug in the OS; in fact a user transferring a very large file can be disconnected during download because of connection timeout on port 21. The disconnect seems to consistently happen after 60 seconds into the FTP transfer.

Has anyone seen this problem before?

Thx in advance.
