Possibly somewhere down in the code perhaps in National Instrument's
TCP/IP VI's themselves, from time to time an attempt is being made to
read or write an array or access an array index with a negative number
of bytes or a negative array index. The error message you are
describing sounds very similar to the message you get if you try to
dimension an array with a negative number of elements. Because of
ones-complement math, A -1 index becomes 0xFFFFFFFF about 4.2 billion
if treated like an unsigned number. When
something tries to create an
array this large it will generally crash.
