[Spacewalk-list] after installation of 3rd party SSL certificate, now getting (intermittent) errors!

[Andy Ingham]

Ever since we switched from a self-signed to a third-party SSL certificate
two days ago (thank you, Heartbleed!), I've seen intermittent issues.

The most obvious error:  the daily 11:00 PM "compare-configs-default" task
(which has always run successfully for all 70+ servers), now is failing
for 98% (but not ALL!) hosts.  The event message when it fails is:  "This
action has been picked up multiple times without a successful transaction;
this action is now failed for this system."

The osa-dispatcher.log and rhn_server_xmlrpc.log show LOTS of entries like
  rhnSQL/driver_postgresql.check_connection('ERROR', "DATABASE CONNECTION
TO 'spaceschema' LOST", "Exception information: Database instance has no
attribute 'dbh'")
clustered around the time of the scheduled run

I've done full restarts of postgres and spacewalk (and even a full reboot
for good measure).

Is there some reason that a cert change would lead to problems with
postgres connections, or is the error above a red herring?

Any ideas of where to look next?

TIA,
Andy
