Is there a maximum file size that DMP 4400G can support. We are trying to upload a 7GB MPEG file to the DMP with an attached 16Gb USB flash drive. However, it fails when it reaches 56% with an FTP error: ( "Unable to write data to the transport connection: An existing connection was

forcibly closed by the remote host.")

Is there a maximum file size that the DMP FTP daemon supports?

  • Cisco Employee,

I am not aware of any File size limitations in the DMP.

I tested with DMP-4400G running 5.2.

I created a 7GB file and used FTP (Filezilla) to upload file to

USB2 on the DMP.

The file transfered without issue. 

I would suggest trying a different file and test

transfer again.

For Example:

(linux, OS X, unix)

command = dd

dd - create a large file for testing



To create a 7 GB file:

# dd if=/dev/zero of=file_7GB bs=7m count=1k



dd if=/dev/zero of=file_7GB bs=7m count=1k

* What FTP client are you using?

* What format type is file?

* What version of code on the DMP?

* What file format is used on the external USB drive?

* What manufacturer & model# of the flash being used?

Thanks Tomas for your thorough response.

I will do more testing as you advised and get back with the answers to your questions.
