sleep-monitor system is about to suspend
On a remote Linux server running XFCE desktop, the server goes down randomly, on monitoring /var/log/syslog, i found the following message

1 2 3 4 5 6 |
Jan 18 05:43:24 sokdesk ModemManager[1300]: <info> [sleep-monitor] system is about to suspend Jan 18 05:43:24 sokdesk systemd[1]: Reached target Sleep. Jan 18 05:43:24 sokdesk systemd[1]: Starting Record successful boot for GRUB... Jan 18 05:43:24 sokdesk systemd[1]: Starting Suspend... Jan 18 05:43:24 sokdesk systemd-sleep[2574]: Suspending system... Jan 18 05:43:24 sokdesk kernel: [ 1217.283955] PM: suspend entry (s2idle) |
When this happens, the remote desktop and SSH connections to the server get disconnected. To get back to the server, I had to restart the server.
The error is fixed by running the command
