Apache running as "init_t" is a call for troubles.
Is it? OK, any idea what caused that and how to fix it?
No, sorry. Your httpd comes from CentOS ?
Yes
Afaik, you should not have any process running in context init_t except init itself. If "ps awuxZ | grep [i]nit_t" returns more than only init and httpd, your problem is likely to be more complicated than a broken configuration of apache.
I've got a few...

I also found at least one file (the audit.log file) which has file type file_t, even though I thought the filesystem had been re-labeled successfully because /var/www/html/robots.txt had the correct type:
[root@g6950-21025 ~]# ls -lZ /var/www/html/robots.txt -rw-rw-rw- root root system_u:object_r:httpd_sys_content_t /var/www/html/robots.txt [root@g6950-21025 ~]# ls -lZ /var/log/audit/audit.log -rw------- root root system_u:object_r:file_t /var/log/audit/audit.log
Any idea (1) what could be causing that and (2) whether it could be related to the problem with all those init_t processes?
It's easy : your init process is broken, all these daemons but init are mis-labeled, so all the files they create (such as log files) are mis-labeled.
And if the next question is "how to fix it ?", the answer is easy too : "I don't have any clue..."
Assuming that httpd came from CentOS, it should be appropriate relabeled. If not, using the semanage -f context would fix it.
This requires some thought. I'll respond back later.
