large fileransfers with libssh sftp_write

["Gigin Jose (RBEI/EIA1)" <Gigin.Jose@xxxxxxxxxxxx>]

Hi,

I am trying to do large file transfers with sftp_write() of libssh.

For file size near to and greater than 300 KB, I get the following error:

[2015/08/18 11:27:27.830293, 1] channel_write_common:  channel_write wrote 32758 bytes
[2015/08/18 11:27:27.833793, 1] channel_write_common:  channel_write wrote 32758 bytes
[2015/08/18 11:27:27.836293, 1] channel_write_common:  channel_write wrote 30306 bytes
[2015/08/18 11:27:27.839293, 2] ssh_channel_read_timeout:  Read (4) buffered : 0 bytes. Window: 1279983
[2015/08/18 11:27:27.840793, 1] sftp_packet_read:  Short sftp packet!
The bytes written is -1
[2015/08/18 11:27:27.845293, 1] channel_write_common:  Remote channel is closed

The byte  written is obtained from the following code segment:
nwritten = sftp_write(file, buffer, bytes_read);
printf("The bytes written is %d\n",nwritten);

Is there any limit  for the ssh transfer using sftp_write() ? I need to transfer large files using sftp. How is this possible ?

Thanks & Regards
