[jcifs] jcifs.smb.SmbException: The handle is invalid

[Mathi]

Hi 

I am getting jcifs.smb.SmbException: The handle is invalid while copying
a file from AIX to windows share directory. This error occurs in the middle
of copying. 

    byte[] b = new byte[4096];
    int i=0;
    
    SmbFile file = new SmbFile(url);
    OutputStream out = new SmbFileOutputStream(file);
    BufferedInputStream bis = new BufferedInputStream(is);
    while ((i = bis.read(b)) != -1) {
        out.write(b, 0, i);
    }

out.write() throws "handle is invalid" exception after some iterations.
Stack trace(JCIFS 1.3.12):
jcifs.smb.SmbException: The handle is invalid.
	at jcifs.smb.SmbTransport.checkStatus(SmbTransport.java:542)

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

I am using JCIFS 1.3.12 in the production. 
1. I tried with JCIFS 1.3.14, but it also gives same error.
2. I tried  with following config(5minutes timeout), but still I get same error.
		jcifs.Config.setProperty( "jcifs.smb.client.soTimeout", "300000");
		jcifs.Config.setProperty( "jcifs.smb.client.responseTimeout", "300000");
		jcifs.Config.setProperty( "jcifs.netbios.soTimeout", "300000");
        
Sometimes I get "Handle is invalid" error while reading file from Windows share
directory.

Could you please help?

Thank you
Regards
