Hi Abhijith,

Thanks for your report.

First, a SIGHUP is not a restart. Do you have any intel that suggests your
instance is actually restarted?

Also, have a look at `/etc/logrotate.d/mailman3`

```
/var/log/mailman3/mailman.log {
	daily
	rotate 5
	compress
	delaycompress
	missingok
	notifempty
	create 640 list list
	postrotate
		if /etc/init.d/mailman3 status >/dev/null; then \
			/usr/bin/mailman reopen >/dev/null; \
		fi;
	endscript
}
```

The postrotate part calls "reopen" if mailman3 is running. reopen is a
control command that sends sighup to the master process, hence the log line.

See `/usr/lib/python3/dist-packages/mailman/commands/cli_control.py` for more
intel.

Can you provide me with more information? So far it seems that your bug
isn't one.

Best regards,

It's far easier to fight for one's principles than to live up to them.
