While maintaining our server on 8/31 - 9/1,
I realized that the average load was around 150.
(That is super high, considering below 1 is normal)
Performance of all services (apache2, git, ..) were extremely slowed down
and sendmail refused any new connections.
Turns out that some service ate all the disk space,
free disk space was almost at zero.
(Thanks to ZFS, I still got access to the machine)
Hours later, the jenkins.log file was found to be of size 1.4T,
wow - the culprit!
Deleted file, updated jenkins, rebooted - and back to speed :)

So in case anybody experiences slow services on jogamp.org,
please post.

Besides, Debian 10's OpenSSL 1.1.1 uses TLSV1.2 as the minimum
protocol. And even if you 'downgrade' that to TLSV1(.0)
and use DH Params of 4096 bits, some email server do not
cooperate (TLS Handshake failed).
So far one email server has been indentified, "orange.fr"
and we send emails to these now w/o STARTTLS at all.
