Huh. OK, I'll look into making that error less obscure then.<div class=""><br>

I am running Ubuntu 12.04 (64-bit). I just tried completely removing<br>
RabbitMQ and all of its dependencies on each server instance and<br>
re-installing (according to the instructions here:<br>
<a href="http://www.rabbitmq.com/install-debian.html" target="_blank">http://www.rabbitmq.com/<u></u>install-debian.html</a>), and the Erlang version<br>
mismatch remains!<br>
<br>
How do I update R14B04 to R16B01?<br>

Hmm, according to <a href="http://packages.ubuntu.com" target="_blank">packages.ubuntu.com</a> Ubuntu 12.04 should package R14B04 rather than R16B01. So either rabbit1 is not running 12.04 (is it running 13.10?) or you have installed from a PPA.<br>
<br>
"sudo apt-cache policy erlang" should help you figure out what's going on.<br>
<br>
Cheers, Simon<br>
