title: SNMP GETBULK Issue: Only could get parts records(Such as 59 records, but there are more than 100 records)
body: <p>I would like to get the interface information for the router by snmp GETBULK, but when I use it, only parts of the record were returned.</p>
  
  <p>The code is below:</p>
  
  <pre><code>public static void main(String[] args) throws IOException, InterruptedException {
      Snmp snmp = new Snmp(new DefaultUdpTransportMapping());
      snmp.listen();
  
      CommunityTarget target = new CommunityTarget();
      target.setCommunity(new OctetString("public"));
      target.setVersion(SnmpConstants.version2c);
      target.setAddress(new UdpAddress("127.0.0.1/161"));
      target.setTimeout(3000);    //3s
      target.setRetries(1);
  
      PDU pdu = new PDU();
      pdu.setType(PDU.GETBULK);
      pdu.setMaxRepetitions(200); 
      pdu.setNonRepeaters(0);
      pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.31.1.1.1.1"))); 
  
      ResponseEvent responseEvent = snmp.send(pdu, target);
      PDU response = responseEvent.getResponse();
  
      if (response == null) {
          System.out.println("TimeOut...");
      } 
      else 
      {
          if (response.getErrorStatus() == PDU.noError) 
          {
              Vector&lt;? extends VariableBinding&gt; vbs = response.getVariableBindings();
              for (VariableBinding vb : vbs) {
                  System.out.println(vb + " ," + vb.getVariable().getSyntaxString());
              }
          } 
          else 
          {
              System.out.println("Error:" + response.getErrorStatusText());
          }
      }
  }
  </code></pre>
  
  <p>After executing it, there are 59 records be returned, but if I use GETNEXT to get them, there are about 197 records be returned.</p>
  
  <p>Any ideas?</p>
  
  <p>Hope anyone could help me, thanks in advance.</p>
