It says that it started building your vignette, but the process was 
killed when it hadn't finished in 20 minutes.

I'd suggest to debug it that you leave the vignette out of the package 
temporarily, but extract all of its R code (using the purl() function), 
and include that script as a test script.  I believe you'll get more 
informative error messages from a test failure than a vignette failure.
