"Out of memory" errors in Safari

[kpturner]

I have started logging these errors in a console (not the browser console but something in our app) with a time stamp and this is what happened:

An unexpected error has occurred at Mon, 10 Mar 2014 22:18:09 GMT:

So the out of memory errors started at 22:18 - which is NOT when the server is down. It is still active at this time - so I have given you a bum steer there. It then happens a few times more, then stops until I interact with the browser again at 09:00. Once our client disconnects overnight, it does not attempt to reconnect until user activity is detected (mousedown, keypress etc). So I got another "Out of memory" error when I attempted to reconnect the LS client. Notice the line number for the error in the morning is different.

Looking at the memory usage for WebKit in the resource manager and it is nothing unusual at all.

The Safari Console shows is attached, reporting a problem with bind_session.js just before the "Out of memory" issue.

The browser itself is not behaving very well now I have this error condition. It is not even rendering properly.
