Dear all,

I have a problem with DJGPP that I cannot solve.

I am using this compiler (on dos) to develop codes for making Monte Carlo
simulations. Actually, I have two codes leading to two .exe files. The first
one - let call it A.exe - is making a simulation with a set of parameters, and
the results are saved (append) to an ascii file. The second one - let call it
B.exe - is a "launcher" lanching thousands of times A.exe with different
parameters (e.g., for making a sensitivity analysis). The two codes are
discussing together through an (other) ascii file where the parameters are
saved by B.exe and red by A.exe each time A.exe is launched.

The system works properly but, after a while, B.exe crashes with the following
message:

Configuration: Too many open files (EMFILE).

I've cheched all my codes and all files opened (fopen()) are properly and
rigorously closed, and there are fsync() and fflush() everywhere.

Can someone help me on that?

Thanks in advance for any help.

Best,
