Hi all,
Does anyone know something about the following
WIN32-apache-modssl and/or WIN32-apache problem as described below?
In short:
It seems that any WIN32-apache (I tried) has this problem:
They cannot display pages (I need mainly https:// but also tried
http://) with many images in a RELIABLE manner.
That means if you SHIFT-RELOAD the page several times
(10x, 20x, 50x.), the apache process crashes once in a while and is
restarted after some time.
In this time the server is not accessable and images remain empty or the
page itself says "unable to load page"
I had this effekt on the following apache servers:
- WIN32-apache-mod_ssl 1.3.6
- WIN32-apache-mod_ssl 1.3.9
- WIN32-apache-mod_ssl 1.3.20
- WIN32-apache-mod_ssl 1.3.22
- IBM http server 1.3.19 - based on apache 1.3.20 (without mod_ssl - but
with own IBM-ssl-128)
I also tried cygwin-based apaches:
- cygwin apache 1.3.6 mod_ssl
- cygwin camp 1.3.20 mod_ssl
The cygwin-based show NOT this effect - but have other problems
(sporadic hangs of the cygwin-apache and/or cygwin-system) which do not
allow to use them.
The only RELIABLE SSL-web server on windows-nt I found yet is
"tinyssl" (also based on openssl) - it is solid as a rock - but it has
not the functionality I need (ProxyPass, RewriteRule, mod_jserv...).
The problem is closely associated with concurrent requests
(to load the images) to the server.
So it is a bug in the thread/process- sychronisation of WIN32-apache
versions and I think in the core-apache,
because apache crashes occur also if you redirect the image loading to
another SSL-server (with ProxyPass) and
also if you use http:// instead of http://..
I need to get a RELIABLE apache-based mod-ssl web server for windows NT
but havent found such a thing yet...
Do you know a RELIABLE (no hangs!, no crashes!) running
WIN32-apache-mod-
ssl installation anywhere?
Is there a solution for this problem?
Thanks in advance
Johannes
Here is a posting to mod_ssl which describes the crashes of WIN32-apache
1.3.20 in more detail:

Hi all,
I use
Apache_1.3.20-Mod_SSL_2.8.4-OpenSSL_0.9.6a-WIN32.zip
from your contribution area
(
http://www.modssl.org/contrib/Apache_1.3.20-Mod_SSL_2.8.4-OpenSSL_0.9.6a-
WIN32.zip
)
when serving SSL pages under this WIN32-apache 1.3.20 under windows NT
e.g: html page with 20 images
or html-frame with 1 image
and I SHIFT-RELOAD these pages several times
(with IE5.5 or netscape4.78 dont matters)
(it depends on timing conditions if the crash will occur -
so several tries - up to 10- may be neccessary)
then I get the following Dr.Watson crashes:
FAULT ->6ffa1522 8b5104 mov edx,[ecx+0x4]
ds:00dfea06=????????
FAULT ->10007587 8b0491 mov eax,[ecx+edx*4]
ds:00000017=????????
because if Apache.exe's are restarted automatically,
the server continues to server after some delay and maybe
anoher SHIFT-RELOAD may show all images/frames.
I think its a problem of serving concurrent https requests
(several images / several frames).
Are there known problems in this area???
How can the problem be fixed?
I tried almost all configuration settings
(e.g. SSLSessionCache on/off, nokeepalive on/off...)
with no effect.
Thanks in advance!
Johannes
