This week using v1.0 I saw some amazing memory leaks using the apache module on Windows (Logging set to debug.), and a simple shell script from a Linux client . The httpd.exe resident program memory size was about 25M at start-up. Simulating 60 concurrent users making one request per second, using the 'echo' sample program. The process memory size jumped to 300M over the period of the tests. So far I have not tried to find where the memory leak is (But it seems S.Uthaiyashankar has), however I am very excited to try v1.1 and make another assessment now that I see a similar issue has already been looked into. I will provide an update with any information and conclusions I discover. Thanks, for the new release.
