Thanks for the report. I wonder when this stopped working—I could have sworn it was working correctly in the past. Anyway, the problem is that arpwatch is calling alarm(2), which is excluded as part of the @timer group in the syscall filtering that is part of the sandboxing options in the systemd unit files. I can reproduce the problem, and I’ll prepare an update to fix it right away.
