Memory leak in Openlayers 8

[sweet369Happpy]

hello, may i know any progress about #9556 （Memory leak in Openlayers 6 beta #9556）， we hit the same issues with Memory leak... could you share some suggestion for us, many thanks!!!

You mean with the same example as in #9556? That surprises me, because there is no label cache any more. Can you maybe provide a reproduction case?

hi ,Thanks your reply， i have a try to update the version to 8.1.0, but still have the Memory leak issues.

my business scene is that frequent loading page and initialization of maps, seems that maps has not been destroyed yet and reload the page, operate multiple times, chrome browser memory usage is increasing rapidly and high. next chrome will crash...

we have destroy the map, code as follows：

    if(this.map) {
      const layerToRemove = this.map.getLayers().getArray()
      layerToRemove.forEach(overLay => {
        this.map.removeLayer(overLay)
        if (overLay.get('layerSourceType') === 'VECTOR') {
          overLay.getSource().clear();
        }
        overLay.getRenderer().dispose();
        overLay.setSource(null);
      })

      const overlayArr = this.map.getOverlays().getArray()
      overlayArr.forEach(overLay => {
        this.map.removeOverlay(overLay)
        if (overLay.get('layerSourceType') === 'VECTOR') {
          overLay.getSource().clear();
        }
        overLay.getRenderer().dispose();
        overLay.setSource(null);
      })
      this.map.setTarget(null)
      this.map.dispose()
      this.map = null
    }
