wrt: mail_version = 2.10.0
I am trying to understand the cause/causes of these log lines:
1) postfix/postscreen[####]: fatal: error [-30986] seeking
/var/lib/postfix/postscreen_cache.db: Success
2) postfix/master[4070]: warning: process
/usr/libexec/postfix/postscreen pid 4366 exit status 1
3) postfix/master[4070]: warning: /usr/libexec/postfix/postscreen: bad
command startup -- throttling
As in the context of these log lines:

The #1 line is confusing in having both the words "fatal" and
"Success". It seems I have seen that discussed in the group before,
(before I installed 2.10.0) but Google is not helping me find the discussion.
All these lines seem to be related to the cases of others who
have reported such errors associated to multiple postscreen processes.
In so far as I understand I do not think I have multiple postscreen processes.
I do recognize that I have 4 ethernet interfaces. eth0 which faces toward the
Internet. eth1 that faces toward CNM internal network. eth2 which is dedicated
to an interface to a filer system (not used by email). lo loopback.
Because I have no code in master.cf to address these interfaces, I think I
am not running multiple postscreen processes.
Here are the uncommented lines of the master.cf:

Aside Note: In the above, from uucp on down, I do not think I need ay of that
but I have hesitated to comment it out as it all exists in
/var/spool/postfix/private/.

Is there a configuration change I must make to eliminate the three
