1) I'd try the script as mod_cgi script to see if it is really a problem 
with apache/modperl. That should be quite simple.

2) I'd recommend updating modperl at least to 2.0.5. In 2.0.4 we had a 
problem that standard file descriptors got closed occasionally. That'd 
mean the next time a file is opened for writing it may get fd 0 for 
example. Many programs are unable to handle this situation.

3) If you are using a threaded MPM like worker I'd try to switch to 
prefork because it is our best tested environment.
