Server troubleshooting

Hi, my server randomly crash sometimes (it kicks everyone without any message and they reconnect automatically).
And also, on joining the server, there’s a delay of like 1s which you don’t have anything and then your phys gun appears, but when your hands are empty and you click and your screen or keyboard your got kicked and reconnected.
