OK, on further investigation, I found that the fail2ban service had not
been restarted by the update script.

So I restarted it, and got the same error as it was stopping, but it
started up ok. After restarting, the error no longer occurs:

[root at system ~]# ps -fC fail2ban-server

[root at system ~]# service fail2ban restart

Hope this info is useful to others...

Cheers
