We have an outbound email notification setup with sendmail. This works fine, but periodically the error Channel: Email::Notification out Can’t use Channel::Driver::Sendmail: #<Errno::EPIPE: Broken pipe>
is reported in the monitoring endpoint.
Simply reconfiguring the notification (clicking Edit
and Continue
) fixes the problem.
Expected behavior:
- This error should not happen.
Actual behavior:
- The error happens from time to time.
Steps to reproduce the behavior:
- Unfortunately we cannot reproduce this behaviour on demand.
What can we do to fix this or to help diagnose it further?
