Hello,
Let me help you with your Apache crashing problem. I am senior Linux administrator and I have had a lot of experience with such problems in the past and I happen to be available at the moment.
First, I will make a bash script that will check if your Apache instance is running, and if it is not, the script will restart it. This script will be useful in any case in the future.
Then, I will find out what exactly is cause your web server to crash and possibly provide you with a working solution for that.
If you want your Apache server running safely, you should hire me for this job,
Thank you,
Alex
