Solved Server crashing, "Allowed memory size of ... bytes exhausted"

My server is crashing almost everyday at night, this is my crashdump I always get:

Code:

Error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes)
File: /src/pocketmine/utils/Utils

[205]         $heap = 0;
[206]
[207]         if(Utils::getOS() === "linux" or Utils::getOS() === "android"){
[208]             $mappings = file("/proc/self/maps");
[209]             foreach($mappings as $line){

[211]                     if(strpos($matches[3], "heap") === 0){
[212]                         $heap += hexdec($matches[2]) - hexdec($matches[1]);
[213]                     }elseif(strpos($matches[3], "stack") === 0){
[214]                         $stack += hexdec($matches[2]) - hexdec($matches[1]);
[215]                     }
[216]                 }
[217]             }
[218]         }

I don't know what you mean with a call stack. Explain.

 

https://ghostbin.com/paste/pr5ve

There's not much more. I already pasted the whole crashdump here, except the part with with hundreds of random letters and numbers. I have no idea what that should mean.

 

I don't know. The server suddenly crashes.

 

Memory leak or something. Just restart server more often!

 

How can I restart my server automatically maybe every 30 minutes? Is there a plugin for that?

 

That is no solution to the problem. It is like hiding that there is a problem.

 

And now? I don't want my server to crash in the middle of the night and my players will be annoyed what is happening. There must be a way to fix this.

 

set main-hard-limit to 0 in pocketmine.yml, thanks me later

 

So, He must enter the configured ram number on the server in the main-hard-limit, and set slots recommended with RAM for no crash.

 

Shall I really set it to 0? Or can I double it from 1024 to 2048?

 

What shall I change now? The main-hard-limit or shall I add an auto-restarter?
