Workaround for Ubuntu guest suspension warning in VMware Fusion

I see this error when I try to suspend an Ubuntu 10 guest in Fusion:

The request to Suspend this virtual machine failed because the corresponding VMware Tools script did not run successfully.

If you have configured a custom suspend script in this virtual machine, make sure that it contains no errors. Attempting the operation again will ignore the script failure. You can also submit a support request to report this issue.

As the dialog states, the second time you try to suspend the VM it ignores the non-zero return code of the script and it seems to work. But it's annoying.

The problem appears to not be VMware actually, but Ubuntu (or Ubuntu's service script). I tried to figure out where exactly Ubuntu's initctl configuration/scripts is broken to no avail but found a work-around that I'm happy with.

A grok pattern for Rails 3.2 logs for use with logstash. Assumes that you have a multiline filter to combine Rails logs into one line and only one worker is logging to a file (c.f. https://gist.github.com/mudge/5063930).
multiline {
tags => ["rails"]
pattern => "^Started"
negate => true
what => "previous"
}
