file transfer failure... or is it?

[bhorn]

We use a 360 Maxx 6T Image Server to store and play back video files. We have one in the office and one in the field, and we use Flash FXP to move files back and forth via an external hard drive. The laptop we use to run Flash FXP here in the office is a newer HP with Windows 7, and it is connected via ethernet cable to the 360. When we transfer files (.mpg or .mxf) from the 360 to the drive, it goes off without a hitch. However, when we transfer files into the 360, the transfer often fails... or it SAYS it fails, but when we check the 360 the file is actually there. This is particularly true with files over 200 MB. Here's the string of messages:
[R] TYPE I
[R] 200 Type set to I
[R] SIZE R_LASPROMO12 test.mpg
[R] 550 No such file or directory
[R] PASV

[R] 555 STOR: no response from handler
[R] Transfer Failed!
[R] SIZE R_LASPROMO12 test.mpg

Any advice?

These are the errors coming from your server.
You did not include timestamp in this log, but what are the time differences between either of these lines and a previous ones?

bigstar might have better ideas, but I have a feeling you'd need to consult support for these devices to see if there's something going on with them.
