ArcMap freezes when running python toolbox in edit session.

I have several layers with the same field name, all of which need to be updated simultaneously. The tool in question  is here:

I start an edit session, and when running it once, it seems to work fine. But after that the tool seems to run endlessly and cannot be cancelled. I have to kill ArcMap in the task manager, and in addition the ArcMap process, since the locks on the database do not disappear when ArcMap shuts down.

In addition, I have to reboot the computer since ArcMap refuses to open after shutting it down via this method. Anyone have any advice on this?
