This is kinda weird... I have a template, it uses a bunch of variables, and has
a for loop. Most of the time, it's fine. But occasionally puppet screws up the
variable expansion.
My template looks like like:
<pre>
<% app_ports.each do |PORT| -%>
##### mongrel <%= PORT %> #####
check process <%= ["mongrel", app_name, app_environment, PORT].join("-") %>
with pidfile <%= ["/var/tmp/mongrel", PORT, "pid"].join(".") %>
group indigo-<%= app_environment %>
start program = "/usr/bin/ruby /usr/bin/mongrel_rails start -d -e <%=
app_environment %> -p <%= PORT %> -P <%= ["/var/tmp/mongrel", PORT,
"pid"].join(".") %>
stop program = "/usr/bin/ruby /usr/bin/mongrel_rails stop -p <%= PORT %> -P
<%= ["/var/tmp/mongrel", PORT, "pid"].join(".") %>"
<% end -%>
</pre>
There's some gnarly redirection around how it gets called, but I don't think
that's the problem. See, what happens is for some fragments, it expands PORT
differently. Like, sometimes the start line ends up with PORT=8005 while the
stop line ends up with PORT=8007. PORT is always consistent inside a given
line, but occasionally inconsistent in a stanza.
The only hint I have, is that this seems more likely to occur if I'm running
puppetd on 2 machines at the same time. But I've only seen this twice, so it's
hard to pin it down. That said, it's a huge problem when it occurs.
