When trying to copy a rather huge (hundreds of MB) file to a really slow CIFS share, from time to time the following happens:

CIFS: Connecting from host [Jenkins-4-35]
CIFS: Connecting with configuration [X] ...
CIFS: Removing WINS from name resolution
CIFS: Setting response timeout [30.000]
CIFS: Setting socket timeout [35.000]
CIFS: copy [smb://.../my.exe]
CIFS: Disconnecting configuration [X] ...
ERROR: Exception when publishing, exception message [Transport1 timedout waiting for response to SmbComNTCreateAndX[command=SMB_COM_NT_CREATE_ANDX,received=false,errorCode=0,flags=0x0018,flags2=0xC803,signSeq=0,tid=2049,pid=59750,uid=2048,mid=5114,wordCount=24,byteCount=195,andxCommand=0xFF,andxOffset=0,flags=0x00,rootDirectoryFid=0,desiredAccess=0x008B,allocationSize=0,extFileAttributes=0x0080,shareAccess=0x0007,createDisposition=0x0005,createOptions=0x00000040,impersonationLevel=0x0002,securityFlags=0x03,name=\X\...\my.exe]]

Apparently the timeout of 30s is not long enough for the file to be completely transferred. Agreed, but the documentation of the timeout options should clearly say that the timeout is actually measured end-to-end for one file and is not a "server does not react at all" type of timeout. This means, it is not enough that the transfer is "life and running", but the complete file must actually be transmitted completely in that time. This is not clear enough in the documentation of the plugin!
