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)

Apache terminates itself

Recently the Apache2 on my Ubuntu computer terminates itself after it is started a few hours, provided that no one has modified any Apache configs or sending out any SIGTERM signal (except apt/apt-get upgrade). When I check the error.log, it shows something like this which I can find no clue:

Why does my XAMPP Apache service keep restarting?

For some reason my XAMPP Apache service keeps restarting. It started yesterday, but I can't really find the cause, because I have made many changes to my PC the day before (windows update, antivirus update, installed new programs, etc).
The XAMPP control panel says that it's running, but when I look at the processes in the windows task manager, I can see that it keeps restarting every second and the windows error reporting process keeps appearing too (without any dialog).
For some reason I can access the xampp first page (localhost or localhost/xampp), but nothing else (no phpmyadmin or anything else I put in htdocs). I have tried to reinstall XAMPP, and it's not the skype issue everyone knows about either. I have windows 8 pro.
The apache error.log keep repeating this:

My best guess is that I've got some kind of spyware with the apps I've installed.
Thank you very much for reading and any thoughts are welcome.
PROBLEM SOLVED:
NVIDIA FirstPacket was blocking it. I've disabled it and it worked like a charm.

xampp Apache 1.8.1 localhost error 404/403

I updated xampp from 1.8.0 to 1.8.1 and things didn't work out afterwards. I googled my problems, tried to change stuff and got more problems in the end.
I don't know what to do with the output in the error.log:

rename .htaccess to htaccess - Either the Problem lies in there or there is some other server configuration issue.
