I think it's imrest. This is the cronjob that causes queries of all registered devices.

$ cat /var/spool/cron/crontabs/root
# Have the monitor retrieve device states for all registered devices once a minute.
0-59 * * * * wget -O /dev/null --header="Accept-Version: 1.0" -q http://127.0.0.1:8165/query/devices 2>&1 >/dev/null

The logs show this to stop after a long run.

$ ps | grep wget
28760 root         0 Z    [wget]

So I think the uap0 goes down and then the crontab has stopped running. imrest is still running and memory/cpu usage is not out of hand yet.

The system is not locked yet, but the uap going down and cron stopped running is concerning.
