Filehandles

[Justin Luster]

I'm using mod_perl 2.0 and Apache::Registry on a Windows XP machine.  I'm using a load tester to test my Perl CGI program.  I'm reading and writing to files and I'm using flock to control collisions.  I keep getting an error when the load tester is going (5 concurrent users).  It seems that the file handles are getting messed up.  The script will write to files that I never write to but only read.    Does anyone know anything about flock and mod_perl?  Have you ever seen file handles get messed up where things are being written to the wrong file?   Thanks.
