HeartbeatPeriod not lower than 30min?
relevant torrc settings of the relay:
```
HeartbeatPeriod 10 minutes
```
After changing this setting I reloaded tor, but heartbeat messages are only logged every 30 minutes.
This is tor v0.2.7.6 on debian jessie.
btw:
I'm logging to syslog via
```
Log info syslog
```
