I attempted to test atom shell using: http://dromaeo.com/
I used a basic hello world app starting point but had to modify browser window options to include:
The test ran for approximately 7 or 8 minutes and then abruptly crashed. The screen went white, but the window stayed open. One of the processes, (I assume render process) terminated in the task manager. No errors were displayed, in console or otherwise. I observed the process memory had peaked around 360mb (according to task manager), though it may have exceeded that before crash.
This is on Windows 7.
I couldn’t find any error events in windows event logs.
