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
