not all mail reports are sent. The process aborts with the following message:
WARNING [2021-05-03 01:21:44] 2328 /app/dbplanet/int/apache-2.4-inst1/htdocs/piwik/libs/Zend/Mail/Protocol/Abstract.php(324): Warning - fwrite(): SSL: Broken pipe - Matomo 3.14.1 - Please report this message in the Matomo forums: https://forum.matomo.org (please do a search first as it might have been reported already)
We use a self-hosted SMTP server.
Sending probably always stops when the server starts to swap.
What can we do?
