Zip file contianing the smbd.log and packet trace for file download
We are using the samba 4.6.14 version. When the file size is more (also seen with lesser sizes), and client has to send more than one READ request to read the complete file. In this case, we are seeing that the READ request is not completing and getting terminated abruptly from the client side. Attaching the packet trace for the failure case when tried with windows client (windows 10) and the smbd.log with debug level 10.
We are seeing this behavior when the file download is tried from windows client (windows 10) as well as with smbclient command.
