I'm thinking that what's causing your httpd process to go zombie is probably a badly-written script. But one other thing that bothers me are the requests to _vti_bin directory. When I was in charge of administering the company's web server some years ago, I found a lot of requests to that directory, including what looked like attempts to run some .exe file. Now, because I was running Apache on a TurboLinux system, I had nothing to worry about. But the logs would show many, many accesses every day.
However, my httpd process did not go zombie, nor was there much impact on performance. (maybe because we were getting only 30 legitimate hits a week when we first went live)

Hi
Can you give us a snippet of your Apache error logs ? Mark down the time that you actually get the zombie process. Is your Apache solely serving static web pages or executing some Perl/CGI/Java/PHP scripts as well ?

Yes mostly all our sites are using Perl/CGI/Java/PHP...Here at 9 pm i am giving the error messages from /var/log/httpd/error file...at that time two processes also became *zombie* - i am mentioning the top and log file...
