@youssefbasha is hosting OpenGamePanel (a free game server control panel) and a Grand Theft Auto San Andreas Multiplayer (a.k.a SAMP, also free) game server through OpenGamePanel on the VPS. He also actually mentioned that this is about his VPS 18 in the OP post. He described the issue there and what he is hosting there, too. He has already tried a few suggested things including downgrading the OS to a previous version.

 Thank you for providing this summary @"Hidden Refuge".  With respect how come some of our sponsors don't allow games servers on their VPSs?  Or make it as difficult as they can for users to run games servers on their VPSs?  I'm not a games expert at all, however it would make sense if someone (like Gigarocket for example) chooses to make a rule against games servers that this has to do with the additional security that is required in order to protect the VPS with the added burden that the VPS has to take.  It uses more resources, it is vulnerable for more security threats and abuse.  Just by the very nature of multiple users being involved.  VPS 8 here is a very good example.  The sponsor has a zero abuse policy in place.  And he cringes when he hears a VPS user is sharing VPS 8 with others.  

As I mentioned in my posts already I really don't have a clue. I have no experience with OGP or/and SAMP. Nor do I have any interest in any of the two. So I'm not really much of a help here. I don't have much time since my normal job started again and my vacation ended to deal with game servers or even in general gaming.

OK understood and appreciated.  

Especially if there is no error to work with when the server is crashing. The only error that @youssefbasha received was related to code of the SAMP server and its HTTP/HTTPS component. I linked to resources regarding that on the official SAMP page. Nothing more I can do. It may cause the crash but there is no real way to test it for me. If the error occures on every server crash... in that case the chance that it is causing the crash is increased. However I have no idea how you can reproduce it yourself to test it. Unless there is a serious issues with the code of the SAMP server I cannot see how a bad HTTP response can crash a game server that is not based on HTTP/HTTPS protocol to begin with. I don't even know what for the HTTP/HTTPS component is used in the SAMP game server. It could be something as easy as checking for a new server version or something else but also maybe something more complex. I don't like poking around in the dark.

 The little bit I came to understand during the discussion this is old software.  Or do I have that wrong?  Manal for example mentioned he was using it a long time ago.  So could it be the more up to date OS is causing errors?  Like it may work if an OS version is used that is more compatible with SAMP, maybe Debian 8 or earlier or CentOS 6 even?

To be honest I don't think that our support forum is suitable to solve such issues. Especially not in the private forum unless any of the staff here is actually a SAMP pro and knows it all (or is a experienced user/developer for it). This isn't the OGP or SAMP support forum. If there are issues related to the OS and its components we can work on that but as soon as it touches something related to a certain software and there is no clear error log or reproduction way there is not much we can do in general as we're not the developers of the software. And always remember that the VPSs are unmanaged products. Such issues are a subject where the provider can simply outright say "No. This is your stuff and you're responsible for it".

I see no real way to test if the VPS is "compatible" with game servers. If there is no network protection in place that would block UDP game server traffic or possibly cause connection issues on UDP (or any other network issues) and there provider is not employing any software or scripts to detect game servers and kill them... Well, any VPS should work just fine to host a game server if it is allowed per ToS/AUP.

Well we're obviously not in an ideal world here.  My main concern is security of the sponsor's VPS that is currently in jeopardy following complaints that have been received from its Datacentre.  There isn't much room to experiment here.  So we're not asking for a scientific answer.  The little I know however is that most experienced Games Server hosts (Lampard would probably be able to say more about this) have additional software on their servers to protect them from abuse that may come from the additional exposure and resource use a games server is subjected to.  So the sponsor should be able to say whether there is sufficient controls and checks in place for the VPS to be able to be used as a games server.  But yes, we do have a member who is very experienced in games servers, so possibly we need to ask him for his input.  Thanks for your input @"Hidden Refuge"
