"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: 
'Error: Out of memory'

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.

The error on the bind_session is related to the <cross_domain_policy> configuration on the server: since the client was working before I suspect that the server is actually correctly configured and thus that error can't be explained.

Try upgrading the client lib to 6.1. I don't think there is anything that could solve the issue there though

Try keeping the client disconnected

Try reducing the size of the bind_session request by modifying the <content_length> element in the server configuration or by manually switching safari to polling. Given the situation this is currently my best bet.

I would take a look to a memory profile, but unfortunately that version of Safari does not yet have a memory profiler.

On my side I didn't reproduce the OOM but I got an unresponsive Safari after a night of DISCONNECTED:WILL-RETRY (I had the log enabled though, my bad).
I'll try to dig deeper, but it may take a while because I'm leaving for a short vacation.

I think I need an idiots guide here
