I tried keepalive on/off with no effect. Also its no pure problem of IE5/5.5/6.0 - the crashes also occur with netscape4.78 or netscape 6.2 Johannes > > Justin > > -----Original Message----- > From: Johannes Bertscheit [mailto:[EMAIL PROTECTED]] > Sent: Saturday, December 01, 2001 9:18 AM > To: [EMAIL PROTECTED] > Cc: [EMAIL PROTECTED] > Subject: MODSSL: WIN32-apache 1.3.x (windows NT) problem of serving > concurrent https requests > > > 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: > > Subject: > WIN32-apache 1.3.20 (windows NT) problem of serving concurrent > https requests > Date: > Wed, 21 Nov 2001 02:20:58 +0100 > From: > [EMAIL PROTECTED] (Johannes Artur Bertscheit) > Reply-To: > [EMAIL PROTECTED] > Organization: > JB Management & Consulting > To: > [EMAIL PROTECTED] > CC: > [EMAIL PROTECTED] > > 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 > > > ____________________________________________________________________________ > __ > E*TRADE - neu in Deutschland.
