When attempting to use zonerunner to edit a TXT record that contains a plus character, BIG-IP DNS presents the error message 'Resolver returned no such record'.


Unable to edit the record.


A TXT record exists with RDATA (the value of the TXT record) containing one or more + symbols


Two workarounds available: 1. Use zonerunner to delete the record and then recreate it with the desired RDATA value 2. Manually edit the bind zone file (see K7032)
