Topic: ssl_module - Refusing connections under load

[ev5unleash]

Hi everyone,

I currently have WAMP installed on a Windows 7 with the specs below:

Windows 7 64-bit
WAMP
-Apache 2.4.4 (Win64)
-OpenSSL 1.0.1d
-PHP 5.4.12
8 GB of DDR3-1600MHZ RAM (2x4GB)
128 SSD
Intel Core i3-3217U @ 1.8GHZ

The problem I am having with this server is that it will stop fulfilling SSL-based requests after a certain amount of time. This server takes about 500-600 SSL based connections at any time so it is under a bit of a load. However, I don't have any bottlenecks in terms of performance. HTTPD.exe takes about 1.5GB of RAM on average and uses about 5-15% of the CPU.

The interesting thing is that the non-SSL virtual servers will respond properly. I can view the server stats via the status_module and access other virtual servers that serve different domains. When I view the status of the server I see a large amount of connections that are stuck in the "_" - Waiting for connection state. My machine that got the "ERR_CONNECTION_REFUSED" error message is also there under "Waiting for connection". So far the only fix is restarting the webserver every 5-10 minutes.

Any ideas?

Thanks,

somewhere in httpd.conf

AcceptFilter http none
AcceptFilter https none

I'm sure you will find in your error log the words Synchronous AcceptEx failed

I added that into my httpd config. Didn't see those words in any of my logs. I put the server in debug during the load and waited for the SSL Vhost to stop responding. Didn't find anything amiss :/

Please post the error log before and while the hanging at pastebin . com so we can take a look at it.

Hello,

I wasn't able to upload to pastebin as it was too big.

I used debug because info didn't give much of anything.

This log is from server start, to rejection connections towards the end, and to closing down the server at the end.

Hopefully someone will see something worth looking into.

Thanks,

I have a same problem , Http protocol and other virtual http hosts work good , but HTTPS / SSL wait for connection .
