Sentinel tests Fail (too many arguments)

[Nutomic]

I'm getting the following error on my node from ./dashman status:

sentinel tests passed    : /home/dash/dashman/lib/dashman_functions.sh: line 1128: [: too many arguments
NO

Everything is working fine, and dashman status isn't showing any other errors/warnings (everything is green). So I'm mostly curious what's wrong here.
