Hi Simon,
  Thanks a lot for your quick update. I just need to start rabbitmq server since one of the application that we are going to test use Rabbit MQ. Since i am new to RabbitMQ, i took this config file from an example and updated.
All i need to do is start the rabbitMQ server for now with minimal option and i have updated the config file as below, but still getting the crash.

{mnesia, [{dump_log_write_threshold, 1000}]},
{rabbit, [{vm_memory_high_watermark, 2.0}]}

Best Regards,

That file contains several errors, of which the most notable is that all
of the RabbitMQ config should be within a {rabbit, Env} tuple, e.g.:

[{rabbit, [{auth_backends,[rabbit_auth_backend_internal]}, ... etc

But almost all of those are defaults anyway. What are you trying to do?

Cheers, Simon
