See the [documentation](https://godoc.org/github.com/cloudflare/tableflip) as well.

The logs of a process using `tableflip` may go missing due to a [bug in journald](https://github.com/systemd/systemd/issues/13708). You can work around this by logging directly to journald, for example by using [go-systemd/journal](https://godoc.org/github.com/coreos/go-systemd/journal) and looking for the [$JOURNAL_STREAM](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#$JOURNAL_STREAM) environment variable.
The logs of a process using `tableflip` may go missing due to a [bug in journald](https://github.com/systemd/systemd/issues/13708),
which has been fixed by systemd v244 release. If you are running an older version
of systemd, you can work around this by logging directly to journald, for example
by using [go-systemd/journal](https://godoc.org/github.com/coreos/go-systemd/journal)
and looking for the [$JOURNAL_STREAM](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#$JOURNAL_STREAM)
environment variable.
