The limit is imposed by memory limitations and not by a fixed number.
What I'd do if I were you is place a breakpoint in Livitestrun.vi, or
set the pause button. The first time the VI is called, it will pop open
the diagram and wait for you to debug. Look at the inputs to the
function and see if they make sense. Is someone passing in a number
that will be used to resize something to a huge size? If nothing is
obvious at this level, turn on execution hiliting and start single
stepping. If the diagram is huge or loops many times, us
e breakpoints
instead, but determine which node runs out of memory and what input
causes it.
Common causes are For loops that auto-index an output and have a huge
number wired to N or have a negative number wired to N. The negative
number is cast to unsigned and becomes a huge number. Initialize array
is anothre place that allocates memory from a number. When you find the
node, correct the logic that produced the huge number.
