> I'm getting an OutOfMemoryError in EigenVerificationJob that seems to come from the following
lines (200 - 204) that try to print the complete eigenvector to the console.
> {code} 
> EigenVector ev = ...
> log.info("appending {} to {}", ev, path);
> {code} 
> Am I doing something wrong here? Or should we handle this somehow else? I don't want
to use another loglevel because of this.
