Hi,
This usually does not have to do with network. The error message usually indicates a crash inside the browser engine, which can be caused by many different issues. For example, it can be caused by out of memory issue (when the page is too large), or a timing issue (when some underlying objects being destroyed too soon), or just a bug in the browser engine. The best way to resolve such issue is to reproduce it first. Once you can reproduce it, you can send a test project to us:

Thanks!
