[rabbitmq-discuss] Max OS X failure on start up / Trivial

[Panayiotis Papadopoulos]

Hi everyone, I know it is trivial but I could not do anything so far, i guess cos i am a noob in Erlang

Anyway I have followed the port install way to install both erlang and rabbitmq. Rabbit is install in the the lib folder of Erland

and erlang loads rabbit

 

2> code:which(rabbit).

"/opt/local/lib/erlang/lib/rabbitmq_server-1.6.0/ebin/rabbit.beam"

Despite that when i start the rabbit by sudo rabbitmq-server i get the usual

Crash dump was written to: erl_crash.dump

Kernel pid terminated (application_controller) ({application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}})

the rabbit.log has this output

=INFO REPORT==== 23-Jun-2009::15:23:02 ===

I have no clue, i am sorry :) But i hope to learn it some day

Hello,

You may have an old database from a previous installation -- if you
don't mind recreating your queues and exchanges, you can delete it, and
the next time rabbitmq starts, it will create a fresh empty database.
The database lives by default in
/opt/local/var/lib/rabbitmq/mnesia/rabbit under macports.

Regards,
Tony

I don't think that's the problem. From the release notes: "When the
RabbitMQ server detects the presence of an old database, it moves it to
a backup location, creates a fresh, empty database, and logs a warning."

In fact the error looks more like it's picking up an ancient version of
rabbitmq - folks were seeing this error 8 months ago when attempting to
run RabbitMQ 1.4.0 or earlier on R12B-5 (or later). See, for example,
http://www.nabble.com/RabbitMQ-starting-problem-on-Ubuntu-td20480353.html

So I recommend searching the system for any remnants of other rabbitmq
installations, in particular rabbit_*.beam files, and remove them.

Regards,

Matthias.

Good point. I just used Spotlight to search for "rabbit.beam" and found
four separate instances. (All of which were, in my case, expected, but
nonetheless it's a valuable troubleshooting hint...)
