Need help with "RAM USAGE ERROR"

[AlmightyMiau]

getting this error:

RAM USAGE ERROR
poison.script@attack (PID - 974)

getServerSecurityLevel: Dynamic RAM usage calculated to be greater than initial RAM usage.
This is probably because you somehow circumvented the static RAM calculation.

Threads: 9000
Dynamic RAM Usage: 1.90GB per thread
Static RAM Usage: 1.85GB per thread

One of these could be the reason:
* Using eval() to get a reference to a ns function
  const myScan = eval('ns.scan');

* Using map access to do the same
  const myScan = ns['scan'];

Sorry :(

The code that is running is:

var target = args[0];
while (true) {
	var moneyThresh = getServerMaxMoney(target) * 0.90;
	var securityThresh = getServerMinSecurityLevel(target) + 3;
	if ((getServerSecurityLevel(target)) > (securityThresh)) {
		weaken(target);
	} else {
		grow(target);
	}
}

The system gives commonly RAM errors on syntax errors. Just a missing tic or parantheses can cause such an error. Maybe you should use 'strict mode'. Then you get really every f*ckin' error.

BTW: Better use const and let for declaration, not var. ;-)

/**
 * @param {NS} ns
 *            ns.args   string   The hostname of the target
 */
export async function main(ns) {

   'use strict';

   const target =
      (ns.args.length > 0 && ns.args[0] === 'string') ? ns.args[0] : undefined;
   const moneyThresh = ns.getServerMaxMoney(target) * 0.90;
   const securityThresh = ns.getServerMinSecurityLevel(target) + 3;
   if (target) {
      while (true) {
	  if ((ns.getServerSecurityLevel(target)) > (securityThresh)) {
		await ns.weaken(target);
	  } else {
		await ns.grow(target);
	  }
      }
   } else {
      ns.tprintf('ERROR :: No target passed. Exiting !!!', '');
   }
}
