<div dir="ltr"><div><div><div><div>Hi Simon,<br><br></div>so we have tried to find the problem with the initial installation, but no luck yet. It is very difficult to track it, as it is totally non-deterministic!<br></div>
In the meantime, we installed the latest version of RabbitMQ, which includes de set -e fix, but the same issue still happened. Given the output of ps auxf<br><br><a href="https://gist.github.com/anonymous/62239513b154179a8a4e">https://gist.github.com/anonymous/62239513b154179a8a4e</a><br>
<br></div>it looks like <br><pre class="">/bin/sh /etc/init.d/rabbitmq-server start<br></pre>and <br><pre class="">/bin/sh /usr/sbin/rabbitmqctl <span class="">wait</span> /var/run/rabbitmq/pid</pre>were running concurrently. Is there any chance that this fact created some sort of race condition between these 2 processes that would make the set -e fix not work?<br>

<br></div>About the system itself, it is true that there has to be something strange going on if a shell redirection can fail, but I'm checking the configuration and I don't see anything specially awkward.<br>

Hi Simon,<br>
<br>
the set -e looks like a very good idea, at least the process will return<br>
the failure straight away!<br>

Sure!<div><br>

These are the ulimits:<br>

[root@ms1 ~]# ulimit -a<br>

<br>
Those are the ulimits which apply to root - maybe they are different for the "rabbitmq" user?<br>
<br>
But more to the point: we're failing to do something very very simple here, there has to be something weird about this system if echo or shell redirection can fail with an error message about memory allocation.<br>
<br>
So have you configured anything unusual about this system?<div><div><br>
