Matthias,<br><br>When 2.8.2 rolled, we also got snagged by this.� It was actually a bit of a mess for us.� Like a lot of companies, we are lean on administrators (500+ servers per administrator) and fast moving.� Rabbit is newer in our infrastructure but its been really stable, so we had classified it as "production safe" for both the application and its packaging.� In our case, we've re-classified the packaging as "development" meaning that when a new version rolls, it has to be manually upgraded (sent through the QA process to test for this sort of breakage.)<br>
<br>Its getting more and more common for our machines to have large memory spaces, and more and more common that applications run almost entirely out of memory.� My guess is that others see the same trend upwards in memory size... so this is probably something you'll continue to have more issues with rather than less.� Given that trend, I'd recommend that the packaging check for this state (if upgrading from <2.8.2) and fail the upgrade if the appropriate values aren't set (i.e. you'll end up with a failed Rabbit at the end of the upgrade.)�� For people starting with 2.8.2+, you might consider re-visiting the hard failure and making this a warning state instead...� seems to me there's a valid argument to throw a warning here rather than blocking (however, I could be entirely incorrect about that.)<br>

We have encountered issues in RabbitMQ 2.8.2 and greater with the<br>
default 'disk_free_limit' monitoring. If you are running on a system<br>
with more available RAM than disk space out of the box, RabbitMQ will<br>
block consumers in its default configuration.<br>

We are surprised by how many people get caught out by that.<br>
<br>
Are there perhaps some popular Amazon EC2 images that are configured with very little disk space in /var/lib?<br>
