Thanks for your reply - I am reassured.
My server is a slow machine with limited memory - not much better than a
Raspberry Pi, but designed to run 24/7 - so it
is not surprising that processes will conflict from time to time.
One warning in eight months is more than acceptable :-)
Thanks again

Yesterday I saw the following warning message in my logs:-
2018-10-06T14:11:19+01:00 geronimo postfix/postscreen[8194]: warning:
psc_cache_update:
btree:/var/lib/postfix/postscreen_cache update average delay is 151 ms
A tenth of a second is an ENORMOUS delay for an SSD, and my immediate thought
