vscode C++ tools keep hogging memory, even though IntelliSense is configured to 1GB. Start this script and get notified when it kills the language server, before your system gets unusable

free-vscode-memory.sh

#!/bin/bash

function warn {
	i3-nagbar -t warning -m 'killed vscode cpp language server' > /dev/null
}

function kill_leak {
	memory_leak=$(ps -eo pmem,pid,cmd | sort -k1 -nr | head -n1)
	
	if [[ $memory_leak == *"cpptools-srv"* ]]; then
		memory_usage=$(echo "$memory_leak" | awk '{print $1}')
		memory_usage_critical=$(echo "$memory_usage > 20" | bc -l)
		pid=$(echo "$memory_leak" | awk '{print $2}')
	
		if [[ $memory_usage_critical != "0" ]]; then
			kill -9 $pid
			warn
		fi
	fi
}

	kill_leak
