Logs and traces from Jan-18 pt1

Here are the traces from two NFS crashes that occurred this past weekend.
Both occurred in the AM (US time) on Jan 18, a few hours apart from one
another.

I followed the instructions I found on the various threads.
There was no output to `rpcdebug -m rpc -c`, not sure what I did wrong
there. The syslog ought to contain the output of sysrq-trigger, however.

The output from trace-cmd captures several days' worth of logs in either
case, but not from system boot.

The syslogs I have cut from ~one hour before the incident until it finished
shutting down prior to reboot. I have removed the output of other services.

Both are VMs on GCE running the 6.1.119 kernel from Debian bookworm (6.1.0-28)
~60Gi memory, 16 CPUs.
