Ok, we are working on a map to display traffic congestion and incidents for an area in Illinois.
The solution we came up with was an WMS overlay (for the congestion segments) on Google maps plus google markers (for the incidents/etc). Every two minutes, the markers are refreshed via an ajax poll, and then the WMS overlay is refreshed. The complaint we have received is that if the page is brought up and remains open in the background for a very long time, IE eventually produces a 'out of memory' error. So, there's a memory leak somewhere that's affecting IE. On my machine, I've never managed to get it to the 'out of memory' error. I identified possible places for the memory leak to be occuring: 1. protoype's Ajax.PeriodicUpdater 2. Google's overlay refresh 3. Google's marker manager The problematic page is: http://www.lakecountypassage.com/index2.html In Drip, I can see a memory leak that starts after a some time and then steadily grows worse. First, I turned off the Ajax poll with PeriodicUpdater and set up a timer to refresh just the congestion segments every 2 minutes. That page is located here: http://www.lakecountypassage.com/index3.html Monitoring that page doesn't show any leaking. So, I turned back on the Ajax poller and congestion refresh via that poller, but turned off markermanager. http://www.lakecountypassage.com/index4.html Maybe there's a very slow leak, but it's nothing compared to the original page over time. Does marker manager have a known leak problem? Is there any way to improve my mm code to address it? I am using marker manager because they want different icon sizes at different zoom levels--is there another solution to the issue?
