<p>This value is used to limit the repetitions processed in GetBulk requests (value == 0 means no limitation). This may be useful to limit the load for a single request. According to SNMP RFC 1905 it is allowed to not return all requested variables from a GetBulk request if system load would be too high. so the effect is that the client will do more requests to gather all data. For the stack this could be useful in case that SNMP processing is done in TCP/IP thread. In this situation a request with many repetitions could block the thread for a longer time. Setting limit here will keep the stack more responsive. </p>
