A minor change of deleting the CNAME and replacing it with an A
record that points at the same IP as the server uses as it's primary
interface (wthout removing the existing A record for hostname or
modifying the PTR record) seems to have resolved the huge numbers
of errors locking mutex.tdb and the associated performance problems we
It doesn't sound like anyone else is experiencing this so I assume the
