The *DB_VIRTUAL value was introduced to allow the clients (presumably ns_clients) that has been running for some time to access the cached data that was valid at the time of its inception. The default value of 5 minutes is way longer than longevity of the ns_client object as the resolver will give up after 2 minutes. Reduce the value to 10 seconds to accomodate to honour the original more closely, but still allow some leeway for clients that started some time in the past. Our measurements show that even setting this value to 0 has no statistically significant effect, thus the value of 10 seconds should be on the safe side. |
