Apache stops responding to http requests -- https continues to work
We have solved a very similar issue on our server. See Apache randomly stops serving HTTPS, but HTTP works just fine
This settings in httpd.conf file fixed the problem:
AcceptFilter http none
AcceptFilter https none

Okay. Very strange problem that I'm having here. I just recently updated to Apache 2.4.2 from 2.2.17, mostly to try to get name-based SSL VirtualHosts working (although they should have been working on 2.2.17). Server is Win2008 R2 (so x64 by definition) running with PHP 5.4.3 and MySQL 5.1.40 (outdated, I know).
When I launch the server, it initially works fine. Responds to all requests, VirtualHosts all in order. However, after an uncertain amount of time (appears to only take a few minutes for the most part, but sometimes takes hours), it stops responding to regular HTTP requests (on any VirtualHost). HTTPS continues to work. No errors in the log, and nothing in the access logs when I attempt to connect.
I'm having a hard time finding the source of this error given its intermittent nature. When removing all SSL-based VirtualHosts, it seemingly increased stability (still responding to HTTP requests twelve hours later). This could be mere coincidence, though.
Entirety of SSL VirtualHost is as follows, should there happen to be a problem with it.
<VirtualHost *:443> DocumentRoot "C:\Server\www\virtualhosts\mysite.net" ErrorLog logs/ssl.mysite.net-error_log CustomLog logs/ssl.mysite.net-access_log common env=!dontlog SSLEngine on SSLProtocol all -SSLv2 SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM SSLCertificateFile C:/Server/bin/apache/apache2.4.2/conf/ssl/server.crt SSLCertificateKeyFile C:/Server/bin/apache/apache2.4.2/conf/ssl/server.key SSLCertificateChainFile C:/Server/bin/apache/Apache2.4.2/conf/ssl/sub.class1.server.ca.pem SSLCACertificateFile C:/Server/bin/apache/Apache2.4.2/conf/ssl/ca.pem </VirtualHost>
Any ideas what I'm missing?

bizna about 9 yearsPerhaps you were searching in the wrong place, since it might have to do with networking. Did you update any other packages when you upgraded Apache? Perhaps something that has to do with networking? Remember: http and https use different ports... Do you have an update about the outcome of your searches?

ajeh over 7 yearsI am in the same boat: upgraded from 2.2 to 2.4 and it started freezing not responding to the requests every few weeks. Same machine and OS, different Apache and PHP. Virtually the same configs with only adjustment for the new versions. Having to restart the service and it works for a few more weeks. Very frustrating.
