Hah... I found the solution. Needed to load the systemd_module. I added this line in httpd.conf...
LoadModule systemd_module modules/mod_systemd.so
... and viola - it works.

Have you made any configuration changes? Does just rebooting the system is causing the issue? The error log does not showing any error.Can you enable the 'debug' level logging and try to restart your httpd service? and share the logs.
From the logs it seems you apache was started but immediately after few seconds it's shutdown.So,something is causing this shutdown.Have you configured any cron job for such service?

Turns out SSLSessionCache was causing the issue
I had to go into /etc/httpd/conf.d ssl.conf
and comment out
#SSLSessionCache shmcb:/run/httpd/sslcache(512000)
my apache server on amazon ec2 crashes for some reason,

what is causing that and what can i do ?
From what you posted, it looks like this the problem:
"Apache exit signal Segmentation fault (11)" [This is what you need to google]
Check if you have enough resources(Memory(free -m) and disk-space).
Then, if still stuck, you may want create dump as explained below and dig into that dump
