FTP Disconnects TYPE A

FTP Server: Filezilla

I have a system that updates our phone systems.  Two sites each with Cisco ASA firewalls have the same phone system.

When we push out update jobs, one site is not staying connected to the FTP server.  Please look at the below logs.  The first connection goes from Type A to Type I and gets the file.

The second once it goes to Type A it disconnects.

Why would it not which to I?
