Thank you. I should have been more diligent/comprehensive previously.
The immediate error is that ods-signer does not find a key (id:
ca7e41658c07917f82ca1a77794a235d) that it is expecting.
May 1 05:35:11 my_server ods-signerd[1960]: [hsm] unable to get key:

May 1 05:35:11 my_server ods-signerd[1960]: back-off task [sign] for
zone my_domain.tld with 3600 seconds
Looking back through the logs however, this is because ods-enforcer
purged that key from the HSM two weeks ago. The signconf file appears
not to have been correspondingly updated though and is therefore now
inconsistent. So I now have:-
In signconf/<my_domain.tld>.xml

I'm guessing the significant error is the key_data_update failure and
that it probably relates to the change made in 2.1.8.
I suspect that just manually forcing regeneration of the signconf would
correct the immediate failure but, as this is occurring on a domain
which is relatively unimportant for me, I would like to try to
understand how/why the situation has arisen and how to correct it
properly/elegantly. I'm also anxious to reassure myself that the same
error is not about to occur on other, more critical zones.

The signer does run for the domain but does not regenerate this
signature.
Can anyone suggest what might be causing this error?
Your log should provide more information. There should be some logging
lines, probably in /var/log/messages indicating that "ods-signer" has
some error. I would suggest a grep ods-signer /var/log/messages.
