"Out-off-bound" error message during FTP transfer | Telit Cinterion IoT Developer Community

When trying to transmit data per FTP using AT-commands with EHS6, I sometime get message "out-off-bounds" (really "off" not "of"):
^SIS: 0,0,2100,"Ftp open(188.8.131.52:21)"
^SIS: 0,0,2100,"220 DS214 FTP server ready."
^SIS: 0,0,2100,"FTP Login OK"
^SIS: 0,0,2100,"put ******20062018-100616.csv"
^SIS: 0,0,110," out-off-Bound\0a"
Has someone an idea?
I can't see this error code in AT commands specification. Can you paste the exact firmware version (ATI1 command reply)?
My suspicion would be that it might be caused by some non-typical or faulty reply from FTP server. Does it happen only with FTP?
To find the cause, I think that it would be very helpful if you could grab some pcap trace on the server side.
Unfortunately it is not possible for me to trace the server
It's not a good news because without a trace we can't in fact say why in this particular case this error happens. Does it happen frequently so that you could easily test with some other FTP server or is it incidental only?
You could also verify with the latest official firmware A-REVISION 00.000.55.
I will try with A-Rev 55
