I created several process builder proceeses around check boxes on the contact object.  I wanted to trigger these to update in mass so I created a hidden checkbox field on the contact object called 'Mass Update', set the value to true for all and trying to do an update. I got the error: The record couldnt be saved because it failed to trigger a flow. <br>A flow trigger failed to execute the flow with version ID 30116000000PPKL. <br/> Contact your administrator for help.

I don't have any active conflicting workflow rules on these fields.  When I tested the active processes they all individually worked. Why am I getting this for all 16K contacts i'm trying to update using Jitterbit?
