Apache 2.0 OpenSSL error

am 18.09.2002 15:04:51 von Estrade Matthieu

Hi,

for few days, i am stressing my apache 2.0.40 with reverse proxy with a=20
tools named Silkperformer.
i have a really strange error, coming up often on some basic requests:

the request is http://web2.test.com/manual/images/pixel.gif

[Wed Sep 18 12:24:04 2002] [error] SSL error on reading data
[Wed Sep 18 12:24:04 2002] [error] SSL Library Error: 336151579=20
error:1409441B:lib(20):func(148):reason(1051)

I tested httpd-2.0.36 and i have the same error, so i tried with openssl=20
0.9.6g and 0.9.6d and the error is still here !
I tested with apache 1.3.26 and i don't get the error.

If i force the client to do HTTP/1.0 on httpd-2.0.36, i still have the=20
errors.
If i benchmark with others product, depending on the product, i have or=20
not the error

I found on google 2 e-mails talking about the same error i have, but=20
it's on apache 1.3 so i don't understand at all.
I will try to find more information about the context of the error.

If someone have an idea,

Matthieu

Unfortunately I don't have the answer, but
I am sharing the same problem.
See the email that I sent to the list a few days ago (attached below).

I am very interested in a solution myself.
Will let you know if I find one first.

Dear mod_ssl group,

We have been trying to use in production the precompiled Apache with mod_ssl
from the precompiled version in the contrib directory:
http://www.modssl.org/contrib/ftp/contrib/Apache-2.0.39-Mod_ SSL-OpenSSL-0.9.
6d-Win32.zip


It behaves very stable over weeks and performs nice under heavy http load.

However when we run load tests over https, the server breaks after a day or
two.
All the log files look normal until the time of the crash.
Only the error.log suggests problems. I have attached it below.

Our system is Windows 2000 Professional with 1G RAM, 2 Intel CPUs.

Appears that when run under load against https URLs, the server gets
overloaded and restarts every few hours.

We are now running it again and collecting CPU and memory parameters over
time, which I can provide if requested.


Your help will be appreciated,


Best regards,

Hi,

for few days, i am stressing my apache 2.0.40 with reverse proxy with a
tools named Silkperformer.
i have a really strange error, coming up often on some basic requests:

the request is http://web2.test.com/manual/images/pixel.gif

[Wed Sep 18 12:24:04 2002] [error] SSL error on reading data
[Wed Sep 18 12:24:04 2002] [error] SSL Library Error: 336151579
error:1409441B:lib(20):func(148):reason(1051)

I tested httpd-2.0.36 and i have the same error, so i tried with openssl
0.9.6g and 0.9.6d and the error is still here !
I tested with apache 1.3.26 and i don't get the error.

If i force the client to do HTTP/1.0 on httpd-2.0.36, i still have the
errors.
If i benchmark with others product, depending on the product, i have or
not the error

I found on google 2 e-mails talking about the same error i have, but
it's on apache 1.3 so i don't understand at all.
I will try to find more information about the context of the error.

If someone have an idea,

Matthieu
