My 0.4.5.10 relay restarts after 4-5 days. No warnings in the log file.

The hardware is ok, Raspberry Pi 4. Has worked before.

Ddos attack?

Now restart after 1-2 days. ☹

```

The last line, “672936 INTRODUCE2 rejected”, sounds bad?

It may be that OS restarts process because it uses too much RAM.  
During DDoS relays [started to consume more RAM, than usually](https://forum.torproject.org/t/memory-limits-for-tor-process/3961), maybe you have not enough it to withstand DDoS.  
Can you try: 1. Monitor RAM usage of your computer. 2. Install latest version of Tor (there were fixes for RAM consumption in it).

Installing the latest version of Tor solved the problem. Also fixed the automatic update so now Tor should update automatically. Thanks
