      Description

      On my unmodified server I encountered a server crash triggered by hostile mobs spawning with no perceivable upper limit.

      One of my regular players has 2 mob spawners that empty into a single area. The spawners are a sekeleton spawner and a cave spider spawner. Before 1.8.3 the server would cap mob generation at a certain point but in this scenario that cap appears to have been ignored. The player left the game to run and within 30 minutes enough mobs had spawned to crash the game. Restarting the server to clear them out showed that 641 hostile mobs had been allowed to spawn while a single player was online.

      It is worth noting that in the past this setup has been able to function without spawning out of control and did not result in enough lag to invoke the server watchdog to kill the server as happened here.

      I have attached the crash report generated by the server with the player names removed.
