# Fixed URLs

## Fixed But Review Recommended
These URLs were fixed, but the https status was not OK. However, the https status was the same as the http request or http redirected to an https URL, so they were migrated. Your review is recommended.

* http://fixprotocol.org/ (301) with 1 occurrences migrated to:
  https://fixtrading.org ([https](https://fixprotocol.org/) result SSLHandshakeException).
* http://erldb.org (UnknownHostException) with 1 occurrences migrated to:

References #1422.

This line is part of the release but not included here

https://github.com/rabbitmq/rabbitmq-server-release/blob/stable/packaging/debs/Debian/debian/rabbitmq-server.service#L16

Fixes #1359

This gives guidances for those users who wish to automatically restart RabbitMQ in the event of a failure. Tested by using the `Restart=on-failure` setting, then running `rabbitmqctl eval "erlang:halt(abort)."`

Neither rabbitmq nor any dependent services in chain actually relies on
syslog, so why keep it?

This tested in Fedora since 2016-01. See this commit:

http://pkgs.fedoraproject.org/cgit/rpms/rabbitmq-server.git/commit/?id=1477671

Nobody complained so far.

Hopefully this patch will fix all systemd-related problems:
- Proxy shell process (which converts signals to `rabbitmqtl stop`) will
  no longer be started under systemd. There is no need in it, as systemd
  unit already contains instructions for graceful shutdown.
- Ready notification for systemd will be sent with the help of `socat`,
  as `systemd-notify` is currently broken for non-root users. `socat` is
  the most lightweight way to do it (other options are using NIF or some
  external helper in Perl).
- epmd will not be able to interfere by sending it's own ready
  notifications.
- systemd journal will contain some additional messages about startup
  and shutdown sequence, just to be sure that everything is working
  correctly.

Fixes #664
