ERROR: Unable to write file : DISK_ERR, leads to Out of Memory errors.

Still fails quickly in v57. So far the most stable version has been v55, where it would run for ~4 hrs.

The code that generated it (simplified down to a single DHT now):

var d;
var e;
var inits=new Uint8Array([0,0,0,0]);
var curdht=false;
var t=-1;
var rh=-1;
var t2=-1;
var rh2=-1;
var fs;
var havetraced=false;



function onInit() {
    digitalWrite(A14,1);
    digitalWrite(A13,1);
    setTimeout("doInit();",2000);
}

function doInit() {
    fs=require("fs");
    fs.appendFile("timetemp5.log","Espruino restarted")
    digitalWrite(A13,0);
    d=require("DHT11dev").connect(C10);
    d.read(function(a){ t=a.temp; rh=a.rh; inits[1]=1;endInit();});

}

function endInit() {
    if (inits[1]==1 && inits [3]==0) 
    {
        inits[3]=1;
        digitalWrite(A14,0);
        setInterval(function() {var mf=process.memory().free;console.log(mf.­toString()+" "+getTime().toFixed().toString()); if (mf < 1100) traceit();doMeasure();},5000);
        setInterval(function(){dologs();},30000)­;
        setBusyIndicator(A13);
    }
}

function traceit() {
    if (!havetraced) {
        havetraced=true;
        trace();
    }
}

function doMeasure() {

        	rh=a.rh;
        	t=a.temp;
        }
    });
}

function dologs() {
    console.log("trying to log...");
    fs.appendFile("timetemp6.log","DHT11,"+t­.toString()+","+rh.toString()+",Time,"+g­etTime().toFixed()+"\n");

save();

Edit: No, unlike previous tests, log files were not normal.
