Severity: 3-Major


Tmm crashes.


Traffic disrupted while tmm restarts.


- DNS module is provisioned - The DNS-Express (DNSX) feature is configured with at least one DNS zone - DNSX is used to try to resolve a DNS query received via a DNS listener - DNSX is enabled as a resolver method in the DNS profile associated with the DNS listener. - The DNS query is received on one tmm thread while another tmm thread is updating the DNSX database files The DNSX database files are updated whenever DNSX performs a zone transfer, or when a new zone is added or one removed from the DNSX configuration. TMM handling dns request while another tmm thread is reloading dns db files (for example, after performing a zone transfer, or when adding/removing a zone from the configuration) This issue primarily affects the DNS module, but it also affects LTM when DNS caching is enabled, such as when using a DNS resolver.(see K12140128)
