# Extensive "Grow heap (frag case)" messages

ShawnCastrianni
USBeta ✭✭✭

My Mono for Android app uses the ESRI ArcGIS thirdparty component that I wrapped myself. Sometimes, after the map loads its shapes, the UI starts to get very sluggish and lots of "Grow heap (frag case)" message start showing up. I assume the heap is being expanded to handle increased memory requirements? Since I am not currently interacting with the app and only the ESRI map has been loaded, I would assume it is the ESRI map requiring more memory to operate? Sometimes it takes as long as 30 seconds for the "Grow heap" messages to stop and then the UI is fast again. Is there anything I can do to prevent this? Is there some way to request that the android process start with a larger memory footprint so that it doesn't have to increase in size so much at the beginning? Any other suggestions?
