That is exactly what I was meaning when I said you should get the E-Stop sorted. On a large machine especially you should never be relying on the software triggering the E-Stop. It is fine to have a signal going to Mach to signal an E-Stop situation but you should also have the second pole on the E-Stop button connected to what is commonly called the E-Stop string. In other words it should drop the circuit to all the contactors to your drives so that they at least stop even if there is an issue with the software not seeing the signal.
I am just having a look at your xml and it seems you also may have Normally open switches for limits and E-Stop would also seem to be a normally open switch, that is a very bad idea as if a connection comes loose or a wire breaks you will no nothing of the fault until you try to use them and they dont work.
Is this machine connected via the parallel port?
I will look further through your xml and see if I can find an issue.
