I am working on a program in MicroSoft C 6.0 that replaces an interrupt handler and then spawns a program which calls the interrupt. The interrupt handler makes calls to a SUN NFS socket library . Problem: The call to the socket library (inside the interrupt handler) hangs the machine. I can see the network indicator flickering ( which indicates the machine trying to access the network). I can also make calls to the socket library before the spawn which works just fine. Has anyone out there had any problems making network calls from an interrupt handler or run into problems like this when spawning programs. Thanks Mark
