Sounds like your system doesn't have enough resources to open file 
descriptors.  (The equivalent of FILES= directive in CONFIG.SYS.)  Does 
the explanation and the advice in section 9.7 of the FAQ help in any way?

It might be educational to write a program that opens its own .exe file 
until `open' fails, and count the number of times it succeeded.  Then do 
the same with `dup' instead of `open', and see what's the count now.
