[CAUSE] A tmnxBsxDnsIpCacheFull notification is generated when the number of entries in a DNS IP Cache is greater than or equal to the percentage value tmnxBsxDnsIpCacheHighWatermark of its tmnxBsxDnsIpCacheSize and the previous percentage value was less than this threshold. [EFFECT] There is no immediate effect, but when the usage actually hits the limit of tmnxBsxDnsIpCacheSize, new entries will not be added to the cache. [RECOVERY] The notification can be cleared if enough cache entries timeout to drop below the threshold, or if the cache is cleared, or tmnxBsxDnsIpCacheSize is sufficiently increased.
