Comment 4 for bug 1556185

So I finally managed to reproduce this:

1. install alpha4, play with it.
2. upgrade to beta2
3. delete all machines (it was a bit laggy experience)
4. try to recommission

What I did next was:

1. stop maas-rackd
2. stop maas-regiond
3. stop postgresl
4. start postgresql
5. start maas-regiond
6. start maas-rackd
7. try to re-enlist machines, and everything worked as expected.

and the issue went away.

Also, I noticed that after I stopped all of the above, MAAS started working faster.. After (7) I delete all machines, and machines deleted really quickly.
