reservedSeatTimeouts Memory Leak

See original GitHub issue

We encountered a suspecious memory leak when using this framework, the reservedSeatTimeouts of Room seems not release in some unkown reasons. The cpu% will grow slowly from 1 to much higher. We inspected the heap dump and found the reservedSeatTimeouts of room stored so many Timeout instances. See below screenshot: leak screenshot It seems in this function the this.reservedSeatTimeouts should delete the reservedSeatTimeout(delete this.reservedSeatTimeouts[sessionId]) when seats reservaltion expired.

Hi guys, on version 0.11.25 I’ve pushed this change, which may fix the memory leak: https://github.com/colyseus/colyseus/commit/49f1c9641411c09a4c26489f7a0bb85950baba5e

Regarding the rooms not being disposed, I do have the same issue on production for some projects, and I don’t know exactly the reason yet. It never happens locally, so it’s difficult to reproduce and find how to fix. The @colyseus/monitor often displays one room with 0 clients, and when I click on “inspect”, there is one stale client in there.
