Bug report: PHP error due to typo with mongodb

[sorano]

Saw this error when I logged into OPNsense today:

Code Select Expand

If you look at the filename it's looking for a file called dahsboard.

Hi,

What about the reports and widget? All works or?

[sorano]

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.
