I am writing a web based submission tool. Now I have a problem that I use extactly the same data to make a submission, sometime it can pass through, some it can not. My perl scripts have no syntax error.I am sure it will print out "Content-type: html/text\n\n" at first line. I have checked the faq about 500 server error. No information explain my problem. The most tricky part is that once the submistion failed, you use "reload" button of netscape and repost the data, it can pass through, but if you use "back" button and submit the form again. It still failed. I am using perl5.002 and ncsa httpd1.5.2a. I found also sometime
my scripts generated core file.
