Transport timeout during transfer of large files

[Thomas Fromm-2]

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]

        at jcifs.smb.SmbFileOutputStream.writeDirect(SmbFileOutputStream.java:245)
        at jcifs.smb.SmbFileOutputStream.write(SmbFileOutputStream.java:216)
...

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,

Hi Thomas,

If we are to believe the error message it seems the server simply did
not respond within the jcifs.smb.client.responseTimeout which by
default is 30000 milliseconds. Try 120000 (2 minutes).
