So I have this tool I've written which takes geocoded address and selects the parcel they are in then updates the shape coordinates and several fields. However on I keep getting a Runtime Error: Cannot Acquire Lock on line 73 edit.stopEditing(True)
According to ESRI this error happens so infrequently that there are no help docs or solutions for this issue.
