When DNS cache is configured on a BIG-IP or BIG-IP Next CNF virtual server, undisclosed DNS queries can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Weakness
The product does not properly “clean up” and remove temporary or supporting resources after they have been used.
