[Worth Lutz]

I'll try to figure that out.

 

Thanks,

Worth

Try to use chrome's timeline and activate the memory track and at the same
time look at the counters section to see where your memory is crashing and
whether the GC is working or not.

This won't solve your problem, it will hopefully help you understand it.

I am pulling map data from my own wms server and am only showing tiles.

Using Windows task manager to see memory, my application starts out with
113,555k of memory.

By zooming and panning it quickly rises to something like 1,771,500k and
then Chrome chokes and goes "Aw, Snap" and I have to reload the page.

What do you mean by large memory? How much?

What map provider are you using? google? OSM?

Are you using SVG features?

I also notice some memory increase (up to 50MB) specially on zoom out that
causes an increase DOM Node Count and Event Listener Count. But eventually
it decreases to 30MB or bellow.

I'm having a problem with large memory use in Chrome and eventually Chrome
crashes with the web page failed.

All I'm doing is zooming in and out and panning to refresh tiles as I change
styles in the mapfile.

Could this be a problem in OpenLayers? I'm using OpenLayers 2.13.

Thanks,

Worth
