## Signals
Systemd supports a watchdog (via the WatchdogSec service file option) which
will send the program a SIGABRT when the timer expires.
Offlineimap handles it in the same manner as SIGUSR2, so that the current
synchronisation is completed before the program exits safely.
This makes offlineimap more flexible and robust for persistent setups that make
use of holdconnectionopen and autorefresh options.
For example, it may be useful in assisting with the occasional situation where
offlineimap may not return successfully after a suspend and resume.
To make use of this, users could add the following to the [Service] section of
their corresponding systemd offlineimap-oneshot service file (restart every 5 minutes):
``` conf
Restart=on-watchdog
WatchdogSec=300
```
