🐞 Bug Report

Description

I updated my client to alpha18 as soon as it was released. After this i left it unattended on my machine which does not run any other service (other than the beaconchain). This morning I imported more validators and attached to my validator tmux session to restart it and saw that it has crashed yesterday evening. There was a clock offset warning. I check "timedatectl".

I checked timedatectl: alarm@atlas01 ~ % sudo timedatectl [sudo] password for alarm: Local time: Wed 2020-08-05 09:13:12 UTC Universal time: Wed 2020-08-05 09:13:12 UTC RTC time: Sun 2020-08-09 09:12:58 Time zone: UTC (UTC, +0000) System clock synchronized: yes NTP service: active RTC in local TZ: no

And NTP seems to be active. However, when I tried to check "systemctl status ntpd" it did not find this service. So I installed the ntp package and started and enabled this service after this.

I'm not sure if the SIGSEGV crash is directly related to this warning though. Stack Trace is included in the log.

Has this worked before in a previous version?

First time encountering this problem.

🔬 Minimal Reproduction

I have restarted the validator and so far it seems to run, but it also ran for hours before the crash.
