SmbException while trying to read from SmbFileInputStream

Hi,

I am trying to read a file which exists on a remote machine using JCIFS 1.3.17 
using the following code:


   {
      long               fileSize                  = 0;
      long               tmpFileSize               = logFile.getLastFileSize();
      SmbFile            tmpsmbFile                = logFile.getSmbFile();
      SmbFileInputStream tmpsmbInputStream         = new 
SmbFileInputStream(tmpsmbFile);
      long               smbFileLength             = tmpsmbFile.length();
      long               l_Count                   = 0L;
      int                ch                        = 0;
      long               skipCount                 = 0L;
      Reader tmpreader = null;
      BufferedReader tmpbufferedReader = null;


		  if (tmpFileSize != 0 && tmpFileSize < smbFileLength)
		  {
		     fileSize = logFile.getLastFileSizeInChar();
		     skipCount = tmpsmbInputStream.skip(tmpFileSize);
		  }
		  else
		  {
		     fileSize = 0;
		  }
		  tmpreader = new InputStreamReader(tmpsmbInputStream, 
charset_);
		  tmpbufferedReader = new BufferedReader(tmpreader);
		  
		  while ((ch = tmpbufferedReader.read()) > -1)
		  {
		     l_Count++;
		  }


		  fileSize += l_Count;
		  logFile.setLastFileSizeInChar(fileSize);
		  tmpbufferedReader.close();
		  tmpreader.close();
		  tmpsmbInputStream.close();
		  logFile.setLastFileSize(smbFileLength);

      return fileSize;

   }
   

occasionally, one of the commands fails, and throws an SmbException with the 
error: "The handle is invalid".
sometimes the exception is thrown from the read() method, and sometimes from the 
skip() method.

is there something i'm doing wrong?

Thanks,
