Reason behind "The resource you request is no longer available"

I've come across people mentioning about the error message -

The resource you request is no longer available: /view/Index.zul (z_t6w). This is normally caused by timeout, or opening too many Web pages. You have to reload the page and try again.

And found a couple of script modifications to be made as the fix.

Now my situation is different. Our product uses ZK-5.0.8 (upgrading is currently not an option) and we cannot modify the jar as it is available on the fly and not locally.

I'm more concerned about what could be the reason behind this error message to come up! Is there any other way I can fix this issue?
