FAN Native ads refresh:java.lang.OutOfMemoryError: pthread_create (1040KB stack) failed: Try again

Question

I met a OOM-issue of FAN native ads with the latest version 4.28.0.I want the FAN native ads refresh every 10 seconds,so I create a new instance of NativeAd and load ad every 10s.Implemented as the official docs says. I reproduced this issue in official demo too.To reproduce easily,I changed the interval time from 10s to 2s. here is the sample code of my test:

private void showNativeAd() {
    nativeAd = new NativeAd(getContext(), mAdunit);
    nativeAd.setAdListener(new AdListener() {

        @Override
        public void onError(Ad ad, AdError error) {
            // Ad error callback
            Log.e(TAG,"failed-->" + error.getErrorMessage());
            //refresh after 2s
            requestDelay(2000);
        }

        @Override
        public void onAdLoaded(Ad ad) {
            Log.e(TAG,"loaded-->");
            // Add the Ad view into the ad container.
            //...

            //refresh after 2s
            requestDelay(2000);
        }

        @Override
        public void onAdClicked(Ad ad) {
            // Ad clicked callback
        }

        @Override
        public void onLoggingImpression(Ad ad) {
            // On logging impression callback
        }
    });

    // Request an ad
    nativeAd.loadAd();
  }

private void requestDelay(int millseconds){
   if (handler == null){
    handler = new Handler(Looper.getMainLooper());
   }
    handler.postDelayed(new Runnable() {
    @Override
    public void run() {
        showNativeAd();
    }
  },millseconds);
}

It is running well at the beginning, but about an hour later,crashed.here is the crash log:
