I feel puzzled about your comment:
Suggestions; revert to OpenSSL 0.9.7, or upgrade to httpd 2.2.x.

I download the following installer from Apache web site:

It uses OpenSSL 0.9.7 alreay and still has the same problem. The summary field
for this bug is "memory leak with mod_ssl and zlib compression" and I can use
the same test sequence to reproduce the problem, e.g. abs -n 100000 -c 149 -f
tls1 https://localhost:443/.

Should I report it in a seperate bug?
