[rabbitmq-discuss] Management plugin(s) crash server at startup

[Julien Banchet]

Hello!

I'm trying to move my actual (working) RabbitMQ node to another, less
loaded, server (actually another VM, hidden from internet, which will
also have a memcache).

So after setting up a barebone 64b Debian6 from a netinst and adding
RabbitMQ repo and installing it I got a working node.

Problem is, the management plugin seems to die, bringing down the
daemon with it after a couple of seconds (immediatly after start,
rabbitmq_ctl status does list plugins, two seconds later it's dead
already):

All plugin files are there, I even compared the CRCs with my actual
RabbitMQ installation (which is another VM, just internet wise +
apache/mysql/etc...) . It's an independant node, no clustering,
replication, nothing special involved. Installing plugins one after
another boils it down to rabbitmq_management being the culprit.

As said, it's a fresh and updated Deb6 64b 2 CPUs, 2Gigs of RAM.

The only diff I can imagine is that no queues/exchanges have ever been
created yet, and there's already an admin user created on it.

Has anyone encountered this? Erlang is a bit chinese to me, I might
have missed an obvious message somewhere, but I can't figure it out
yet :-)

Thanks in advance,
