Hmmm then it's a problem... the process shouldn't check if it is outdated or not
(or could check but in that case disable the corresponding ciphersuites, instead
of generating the key). The easier way to fix that is to generate the
RSA key and
the DH parameters by other means --say certtool running on the bg once
per day or something like that.
