[jcifs] Transport timeout during transfer of large files

[Thomas Fromm]

Used jcifs version: 1.3.10

Hi,

I receive an error when transfering files with size of ~50MB:

jcifs.smb.SmbException: Transport1 timedout waiting for response to 
SmbComWriteAndX[command=SMB_COM_WRITE_ANDX,received=false,errorCode=0,flags=0x0018,flags2=0xC803,signSeq=0,tid=2055,pid=1230,uid=4099,mid=18048,wordCount=14,byteCount=2049,andxCommand=0xFF,andxOffset=0,fid=16384,offset=17602560,writeMode=0,remaining=0,dataLength=2048,dataOffset=64]

This error does not appear always.

What are the circuumstances to get this error and how to resolv it?
Just increase timeout values?

Thanks in advance,
