Its Blackhat, so it does bad things, just a quick Google returns bad reviews.
So, it looks like it doesn't limit the connections (like good bots), just bombards URLs in one go.
DirectAdmin and System Crash

Yea it's blackhat and just a simple program.
There should be some way to cover it up because websites just don't crash with this software but even without it because it's also just sending requests in some way.
And when I've tried to run this on shared hosts, they don't crash for even a second. And tried it on DA's file website, that crashed. Maybe the shared hosts have old version apache and the newer one has a bug ? Or they have optimized it quite right.

Perhaps its a resource issue, VPS containers hardly have any - well, when I had one, I was only allocated 350MB ram on a 8GB node/server, this was going back 5year though, maybe VPS technology has improved.
I'd test the programme, but 1. I wouldn't trust it as it may install adware etc, and 2. I have no test server to test.

Well my VPS has full resources because I have a windows dedicated server on which I run VMware to host only a single VPS. So the resources are available all the time.
But yes,
I will try on another VPS to be sure about the Hardware.
Then we are left up with Apache .
Perhaps back-end and front-end can help ? What do shared hosts do for a securing ?

Searching Google shows my own topics on different forums. Can't seem to find any proper solution. Every night I sleep, a friend's SMS wakes me up that our websites aren't working. I wake up to check the server console, and I find the same hung_task_timeout_secs messages for all the processes that can't find enough RAM. And of course all Real RAM in use and Swap still free. 
Maybe SMtalk can do something or anyone else ? I can pay $10-15 for someone to personally be on the system and mitigate the issue.

I don't understand.... Is someone using PRStorm "legitimately", or does the server (or VPS) crash by itself over time. If the latter, then it could be a (VPS) config error - how do you get it back up, reboot?
I did some research quickly and can see this program can get sites banned from Google and AdSense.

Well.
I change my website configs daily, make new additions and check it with PRstorm ( which sends any number of requests to the site you like ) but it still crashes.
Basically, I use this software just to check because this is not the one which is the cause of crash. My website crashed even before I used this software. At night, I get heavy traffic. Not that heavy but, its like 60 parallel users and apache crashes.
So PRstorm is actually not related to it, since of course I cannot find 60 users online everytime I want, so I use PRstorm to check what happens when the same 60 people come again. Only difference is, in the /server-status page, when 60 users are legit people, they have different IP's and when it's PRstorm, its a single IP of the machine that connects.
So on 60 parallel users, I see there are tons of apache processes that open up and eat up all the RAM. However, swap and CPU is still free. But websites don't show up. When all ram gets used up, system shows the same hung_task_timeout_secs messages which are actually out of ram errors. So restarting apache fixes it. It doesn't require system restarts though. Not sure why the swap ain't being used.
Also, I believe there is a certain type of connection that arrives and apache processes start growing. There are 2 methods to check online users, One if whois.amung.us and other is /server-status page. When there are 50 online people at amung.us /server-status page remains at 10 connections but sometimes even when amung.us shows 50, /server-status page also shows 50 and that's the time when it crashes.
Also, if people don't like giving me the address of their website because many don't want PRstorm to be run on their site, so please share any other software which can make legit requests to the URL's we specify. Many would be available which can serve the purpose I believe.
