-- RESOLV::lookup returns an empty string. -- TMM might crash.
RESOLV::lookup does not return the expected result; tmm might crash. Traffic disrupted while tmm restarts.
An iRule runs RESOLV::lookup targeting the query toward a local virtual server. For instance: RESOLV::lookup @/Common/my_dns_virtual www.example.com
In the RESOLV::lookup command, replace the name of the virtual server with its IP address, or the IP address of an external DNS server. For instance, if /Common/my_dns_virtual has destination 192.0.2.53:53: instead of this: RESOLV::lookup @/Common/my_dns_virtual use this: RESOLV::lookup @192.0.2.53
