Re: Running two errands simultaneously

The short answer is “yes”. Yes, BOSH blocks the whole deployment while you run errand [1].

As far as I see, the main reason hear is consideration that BOSH errand job can perform operations on deployment. For instance you can take admin-ui tool, that use errand job to register himself into UAA [2]. Performing any updates on the deployment that runs errands can cause errors that are hard to debug.
