Re: [munin-users] spoolfetch failing for certain nodes

[Peter W. <pe...@sc...>]

I'm experiencing the same thing. I cannot figure out why it is failing. I
did just upgrade from Ubuntu Saucy (2.0.17-2ubuntu1.1) to Ubuntu Trusty
(2.0.19-3), but I can't see a pattern in why it works or not between some
nodes and not others.

I have checked exactly the same usual things as Gustavo.

I've searched for the error and Gustavo's post is the only useful thing I
find.
