[Samba] Samba drops connection on "large" files 2GB+

[Leon Benthaus]

Dear all,

I still have CentOS7 running with the latest Samba Version available for 
it (samba-4.10.16-20.el7)
I'm experiencing a really strange issue. When I copy a file larger than 
2GB I  always get a network
drop. It just stops at around 1,74gb. The logs didn't show something in 
default logging level and
are overwhelming at 5. An interesting detail is: If I pause the copy 
process every other second
I can get the whole file copied. If I let it run at full speed it is not 
working. Any idea? I already
played around with socket options and stuff. No change. The shares is 
located on a xfs formatted drive.

Thanks in advance!
Best, Leon
