[systemd-devel] Watchdog problem

[Mikael Djurfeldt]

Hi,

I couldn't figure out a better place to ask this question. Please point me
to another place if you have a better idea. (Perhaps I should bring it up
with VirtualBox developers instead?)

I run Debian buster (with some upgraded packages) as a Virtualbox guest
with a Windows host.

When the host has gone to sleep and wakes up again, I get logged out from
my gdm session. It starts out like this:

Sep  7 13:23:58 hat kernel: [82210.177399] 11:23:58.337557 timesync
vgsvcTimeSyncWorker: Radical guest time change: 2 491 379 233 000ns
(GuestNow=1 567 855 438 281 378 000 ns GuestLast=1 567 852 946 902 145 000
ns fSetTimeLastLoop=false)
Sep  7 13:23:59 hat systemd[1]: systemd-logind.service: Watchdog timeout
(limit 3min)!
Sep  7 13:23:59 hat /usr/lib/gdm3/gdm-x-session[1285]: (EE)
Sep  7 13:23:59 hat /usr/lib/gdm3/gdm-x-session[1285]: Fatal server error:
Sep  7 13:23:59 hat /usr/lib/gdm3/gdm-x-session[1285]: (EE) systemd-logind
disappeared (stopped/restarted?)

Can I fix this by setting systemd-logind.service WatchdogSec to something
else? What should I set it to to disable watchdogs? I tried to find
documentation for WatchdogSec but failed. Can you please point me to the
proper documentation?

Best regards,
Mikael
