Comment 16 for bug 856764

Quick update on this... I will probably submit this patch upstream, but the channel_errors object seems to exist in the old kombu, so we can declare it without an error, but it doesn't get populated as that version of kombu doesn't populate it.

The supplied patch should "work" on any version, but will only detect channel_errors when running versions of kombu which support it.

Doubtlessly this could be cleaner, and I still think that adding heartbeat support to actively populate and check the channel would be worthwhile, but this should also help with the issue in the short term.

It's also worth pointing out that the newer versions of kombu inherently support a lot of the functionality we're duplicating, such as ensuring connections exist, pooling connections and determining which servers to use and in what order. It's probably worth looking at implementing those once the newer versions of kombu are "standard" on the bulk of distros.
