Repeated Death

Yesterday I was playing on the multiplayer server Swag Craft and my game crashed from "not having enough RAM". I did a little research to understand what had happened, however I did nothing about it. Today, after doing a little singleplayer, I went back on to Swag Craft and was immediately presented with the "You Died!" screen. I hit "Respawn" and was just taken back to the same "You Died!" screen. This happened several times. I am not sure if this specifically has to do with this server or if it's all of multiplayer that it would have happened on.
I did not attempt to enter any other servers after this.
I also did research on the internet, but could not find a similar problem. Thanks.
