OutOfMemory exception

When I click `Run Code` I'm getting:
```
[0.019s][warning][os,thread] Failed to start thread "Unknown thread" - pthread_create failed (EAGAIN) for attributes: stacksize: 195316k, guardsize: 0k, detached.
Error occurred during initialization of VM
java.lang.OutOfMemoryError: unable to create native thread: possibly out of memory or process/resource limits reached
```
