photon is making variable of the room automatically false

I saw your question in Discord, too. If you must crosspost, please include links or tell us otherwise that you asked in other channels, too. In best case, avoid crossposting. Thanks.

For players, who are still in the room, a rejoin is possible, even if the room is closed and invisible (in matchmaking). You may want to set a PlayerTTL to extend how long someone can rejoin and after a disconnect, you may want to use ReconnectAndRejoin.

There is no code to randomly close rooms but if you fill the event caches and or properties (topic: sending too much), the room may indeed get closed. You may want to check if you sent lots.

Sadly, it is a bit of work to get specific numbers, so usually you'd try to not let it grow by much and test.

Anything in the cache will have to be sent to joining clients, so it is good practice to keep it lean anyway.

If you want to, you can accumulate the stats every time you send something. There is the ByteCountLastOperation (in the LoadBalancingClient.LoadBalancingPeer) which you could check after raising an event that is being cached.
