Apache graceful restart

We have an issue with apache graceful restart and we are on 2.2.3 version with 1.1 weblogic proxy plugin on linux 5 environment.

We gracefully restart apache at 4 am daily and after couple weeks we see the apache server hung(its not serving any requests). We think the below forum solves our issue but not sure where to find prefork.c file to edit what they say in that forum. Any thoughts??

https://issues.apache.org/bugzilla/show_bug.cgi?id=42829

 

There could be a lot of different reasons, but records from the logs would help to find the problem.

 

Here is the debug log from apache server. Initially it says SSL is configured for the request and then it says SSL is not configured. We only see this issue when we do graceful restart of apache server.

Please try to add below lines under /etc/httpd/conf.d/ssl.conf :
<VirtualHost irm.company.com>
# Setup SSL for irm.company.com
ServerName irm.company.com
SSLEngine On
SSLCertificateFile /oracle/secure/irm.company.com.crt
SSLCertificateKeyFile /oracle/secure/irm.company.com.key
SSLCertificateChainFile /oracle/secure/gd_bundle.crt
</VirtualHost>

Then restart apache.

 

We already have the above mentioned SSL configured. Thanks for the reply though.

 

#Make sure that you specify the port for both http and https ie.
NameVirtualHost:80
NameVirtualHost:443
#and
<VirtualHost *:80>
<VirtualHost *:443>
#mixing * and *:443 does not work it has to be *:80 and *:443

 

yes we already have the http/https declared aswell. Our config looks good as we are using the same config in production and we dont see any issues. We think the issue is with the graceful restart we do daily at 4am. So the link provided above has a similar issue discussed but im trying to find out how to apply that patch mentioned in the above forum.
