Cause

The cause is an unresponsive mod_nss.d process.

Resolution

1.Stop Apache:

service apache2 stop
 

2. Check for any remaining mod_nss.d processes using the ps command:

ps -ef|grep mod_nss |grep -v grep
 

If there is no output, there are no remaining processes - Go to step 4.

If there are any remaining processes, the output is similar to the following:

root      6671     1  0 16:28 ?        00:00:00 /usr/sbin/nss_pcache 15466514 off /etc/apache2/mod_nss.d
 

3. Kill any remaining processes and repeat step 2 to verify that there are no remaining processes.

Example based on the sample output above:

kill 6671
 

4. Start Apache:

service apache2 start
 
Note: It is not sufficient to restart Apache. It must be stopped and then started.
