This is the expected behaviour: when the system is running out of memory (currently less than 30% available memory), the browser will start unloading background tabs to free up some memory, thus hopefully avoiding the entire application being taken down. Those tabs, when focused again, need to be reloaded. Note that the data is cached, so depending on server parameters, this might not imply data consumption (for highly dynamic webapps it almost certainly will though).
