@ManeeshaS294 Is this a new issue? Is so, did something change between the tests running and failing?

Memory crashing the browser can have several causes, including a memory leak within the application under test itself, so it's impossible for us to assess the cause without a reproducible example.

Without any knowledge of your test suite, the first thing I'd suggest is reducing the size of a single test.
