samba - Oct 2018 - Large file (over 4Gb) transfer problem from Windows to Samba 4.7 on CentOS 7.5

Dear All,
Previously I setup CentOS 5 Samba server and everything fine
But now I install CentOS 7.5 setup Samba 4.7.1 and faced the following problem
.
When I file less than 4 Gb ... all OK.
But when I transferred file larger than 4 Gb, Samba truncated to 4Gb
exactly and Windows OS side see as zero byte file.
In CentOS7, can see as 4 Gb but file was corrupted
Let me know what the problem could be

Best Regards
Mr. Linux CZ

Sorry, but you are going to have to give us a lot more info here, how
are you running Samba ?
What is in smb.conf ?
What Samba version did you upgrade from ?
