[rabbitmq-discuss] Rabbit MQ Crash

[Michael Sander]

Hi Matthias,

Full logs are attached.  You'll notice that it crashes pretty often now.

Here are the output of the commands

$ sudo rabbitmqctl eval 'rabbit_misc:os_cmd("/bin/df -kP
/var/lib/rabbitmq/mnesia/")'
Error: syntax error before:
$ /bin/df -kP /var/lib/rabbitmq/mnesia/

  3437664      65% /


I just noticed the following in the non sasl log, I should have included it
in the original:

=ERROR REPORT==== 7-Apr-2014::10:08:34 ===
