Couldn't read packet: session disconnected by remote ssh daemon--:--

[Jprakash89]

I'm facing this SFTP error "Couldn't read packet: session disconnected by remote ssh daemon--:--" for GET command to download a file from a file server from HP Nonstop Tandem server.

This error occurs ONLY when we try to download files bigger than 100,000 Bytes.

Could you please suggest if any settings need to be done on HP NONSTOP side or on file server side ? 

Log sample:

$ABC SUBVOL 2> sftp  /name $XYZ3/ -S $SSH FILEPROVIDER@ssh.FILESERVER.com

SFTP client version T9999L02_31MAR2022_comForte_SFTP_10_15_0

Connecting to ssh.FILESERVER.com via SSH2 process $SSHB3 ...

Secure Connection is ready to initiate File Transfer

sftp> cd folder

sftp> get file1 $ABC.SUBVOL1.FILETEST

Fetching /folder/file1 to /G/ABC/SUBVOL1/FILETEST

Hi,

Were you able to solve this issue?

Workaround, if you are using sftp -R 5 -S $<ssh2> username@hostname

Specify a lower number for -R [num-requests] option.

Thank You!

Thanks a lot for your suggestion. I tried to include -R option which resolved the problem of "Couldn't read packet: session disconnected by remote ssh daemon--:" 

Alternatively I tried with Buffer Option -B (-B 29696)  which also resolved the issue. So we decided to go with including -B in SFTP cpmmand.
