Agent Daemon won't start on Linux Ubuntu 18.04 64-bit

[gpedro]

Hi there,

I have been using Pulseway for some months now and everything was good until yesterday when I rebooted the machine the agent is running on.

This machine went throught Linux updates some days before so I think this is related.

What I experience is that when the service starts, reads the configuration, but after a second the daemon exits with code 11 as you can see below.

● pulseway.service - Remotely Monitor and Control IT Systems
   Loaded: loaded (/etc/systemd/system/pulseway.service; enabled; vendor preset: enabled)
   Active: failed (Result: signal) since Sat 2019-08-03 23:42:38 WEST; 1s ago
  Process: 23493 ExecStart=/usr/sbin/pulsewayd --no-daemonize (code=killed, signal=SEGV)

ago 03 23:42:38 BLUEMONSTER systemd[1]: pulseway.service: Failed with result 'signal'.

I actually think it starts the daemon, as I get the notification in the app telling me that the machine went offline, which means the status had to change to online somewhere along the way, right?

Does anyone have an idea of what may be wrong with my setup?

Below is a copy of my config.xml
