The download goes on after a wait interval:

Please change the try/catch blick around the line

downloadHandler.processDownload();

in DownloadEngine.java to:

try
{
downloadHandler.processDownload();
}
catch ( MalformedURLException exp )
{
failDownload();
candidate.addToCandidateLog( exp.toString() );
candidate.setStatus( CandidateStatus.CONNECTION_FAILED );
// might need to handle different cases on some try again on others
// remove
NLogger.error( DownloadEngine.class, "Error at Host: "
+ candidate.getHostAddress()
+ " Vendor: " + candidate.getVendor(), exp );
}
catch ( IOException exp )
{
failDownload();
candidate.addToCandidateLog( exp.toString() );
candidate.setStatus( CandidateStatus.CONNECTION_FAILED );
// might need to handle different cases on some try again on others
// remove
NLogger.warn( DownloadEngine.class, "Error at Host: "
+ candidate.getHostAddress()
+ " Vendor: " + candidate.getVendor(), exp );
}

and try again. This time you should get a full exception stack in the error log file.

The other option is to raise the error log level to WARN.
