[rabbitmq-discuss] RabbitMQ shuts itself down every night?

Wed Jul 11 06:38:55 BST 2012

Hey everyone,  

For a project I'm using RabbitMQ and I've encountered a strange problem that I'm unable to solve. The rabbit-server will automatically shut down every night with the following logging (I cleaned the log files and just waited for the next shutdown to occur :)):

shutdown_err:
Error: {'EXIT',{error,{could_not_read_pid,{error,enoent}}}}

shutdown_log:
Stopping and halting node rabbit at lukas …

startup_err:
/usr/lib/rabbitmq/bin/rabbitmq-server: 90: erl: not found

startup_log is empty

rabbit at lukas-sasl.log.1:  
=SUPERVISOR REPORT==== 11-Jul-2012::04:33:51 ===
     Supervisor: {<0.720.0>,rabbit_channel_sup_sup}

     Reason:     shutdown
     Offender:   [{pid,<0.722.0>},
                  {name,channel_sup},
                  {mfa,{rabbit_channel_sup,start_link,[]}},
                  {restart_type,temporary},
                  {shutdown,infinity},
                  {child_type,supervisor}]

Halting Erlang VM

I'm using a plain version of RabbitMQ 2.8.2 on Ubuntu 10.04.4 LTS, so far I've only installed RabbitMQ without changing the configuration. Also, the app hasn't been released for testing yet, so there's been no traffic over RabbitMQ...  

After re-starting Rabbit, this is the output of rabbitmqctl status:

 {uptime,20}]
...done.

I've searched the internet for a while now, but so far I wasn't able to find anything -- perhaps someone on this mailing encountered the same issue and has a solution?

Thanks!

Kind regards,
