Some nodes got fenced and rebooted right after nightly "Update package database"

So last night two nodes in the span of 4-5 hours were fenced and rebooted right after the 'apt update' cron/timer ran.
The log has:
5:05:19 Fnished pve-daily-update.service
and then
at
5:05:22 - client watchdog expired and a reboot.
In the meantime there are few errors about pmxcfs status notice RRDC update error on rrdcached files.

Any idea what might have caused it and how to prevent it? The nodes are running

pve-manager/8.2.2/9355359cd7afbae4 (running kernel: 6.8.4-3-pve)

Thanks in...
