SIGSEGV on 15.1.10.x

After some digging I found that issue was caused by standard TCP virtual server with DNS profile attached

ltm profile dns TEST_dns {
    app-service none
    defaults-from dns
    unhandled-query-action drop
    use-local-bind no
}
ltm virtual-address 192.0.2.1 {
    address 192.0.2.1
    floating disabled
    mask 255.255.255.255
    traffic-group traffic-group-local-only
    unit 0
}
ltm virtual TEST_tcp {
    destination 192.0.2.1:domain
    ip-protocol tcp
    mask 255.255.255.255
    profiles {
        TEST_dns { }
        f5-tcp-lan {
            context serverside
        }
        f5-tcp-wan {
            context clientside
        }
    }
    serverssl-use-sni disabled
    source 0.0.0.0/0
    translate-address disabled
    translate-port disabled
}

No matter this config is applied to active or standby device - after some time device cores

Currently we have 29 zonerunner zones, 27 dnssec signed zones and 36 wide IPs

Disabling DNSSEC or GSLB or DNS Express does noting

Hope someone could point F5 Product Development on this thread and maybe they could fix this issue with next BIG-IP releases
