Is it possible to make java Runtime.getRuntime().exec to work properly in WLS?

[metorm]

I managed to run xfce4 properly on WLS, i.e. bash on windows 10. Everything was find until I tried to run Pycharm/liclipse on it.

The GUI loaded normally, but both IDE failed to run python executable. The error message says

java.io.IOException: error=12, Cannot allocate memory

I spent some time on the maximum allowed memory of JVM, but it turned out that the problem was caused by WLS, it seems that WLS doesn't take fork() call properly.

Here is the test code:

import java.io.IOException;

public class prova {

    public static void main(String[] args) throws IOException {
                Runtime.getRuntime().exec("ls");

    }
}

This code has only one line, but when I tried to run it, I got below error message:

Exception in thread "main" java.io.IOException: Cannot run program "ls": error=12, 无法分配内存
	at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048)
	at java.lang.Runtime.exec(Runtime.java:620)
	at java.lang.Runtime.exec(Runtime.java:450)
	at java.lang.Runtime.exec(Runtime.java:347)

	at java.lang.ProcessBuilder.start(ProcessBuilder.java:1029)
	... 4 more

Obviously, java will not be able to load any native executable.

Is there any way to do with this?

Hi @metorm -- I assume you're referring to "WSL" ("Windows Subsystem for Linux")? This sounds similar to #1403 . Could you try the workaround on that ticket?; does it help you?

[metorm]

Thanke you @aseering . I have read #[1403].

My RAM is 8G, and pagefile was managed by the system before. I fixed the pagefile as 8G and it solved my problem.

However, Now I only have less than 10G in my SSD. I wish some one can solve this completely.

Closing as a duplicate of another issue (which has been fixed :)) #1403
