Saw this error when I logged into OPNsense today:
[28-Jun-2021 22:47:18 Europe/Stockholm] PHP Warning: unlink(/tmp/mongodb_dahsboard60da35511c350.json): No such file or directory in /usr/local/opnsense/mvc/app/controllers/OPNsense/Sensei/Api/WidgetController.php on line 97

If you look at the filename it's looking for a file called dahsboard.
Hi,
What about the reports and widget? All works or?
Well, the mongodb service had stopped again for some unknown reason.
Just starting the service normally (without erasing reporting data) got it up and running.
However I seem to get alot of mongodb stops for no apparent reason, the fw is up and running all other services works fine but mongodb keeps taking a dump from time to time.
Edit:
Looking at this further I found the following:
root@fw01:/var/log # grep -i mongod dmesg.*
dmesg.today:pid 20481 (mongod), jid 0, uid 922, was killed: out of swap space
dmesg.yesterday:pid 20481 (mongod), jid 0, uid 922, was killed: out of swap space
So out of memory seems like a solid guess, just weird that no other services was affected. I have 8GB RAM and 2 days retention for Sensei.
Looks like Suricata is using alot of RAM though.
