Kian:
The problem you have looks like the memory "housekeping" is not being done. That is, the images loaded and then "closed" are not being closed. As more images are opened indeed there is no longer any memory left. The TCP/IP problems mentioned by Stephane and I were related to errors we made while communicating. There was nothing wrong with LabVIEW or any of the TCP calls! My (Dave Korpi) particular problem is I was asking to read a TCP message with more bytes than are allowed. I did this because I improperly measured the string length! Nothing wrong with Windows NT either.
Strive to close the images, make sure arrays are properly closed and the vi is configured to "release memory" after executing.
Good luc
k!
