Same here. A few days ago, daemon for a couple Debian servers just randomly crashed around 0300 and will not start again. Tried to remove and re-install but nothing. Pretty sure an update for Pulseway was pushed that caused it. There were no changes/updates on the systems that could have caused it. Installing current version does not fix it, even after purging install.
