Embedded Services Stopping
-
We have multiple PFSense Embedded units out in the field. But the problem we are having is after about 3-6 months we get a call from the customer that the unit isnt working. We remote into it and that unit is up and working fine except the DHCP DNS NTP and SIP Proxy services are all stopped and wont start back up. We then go down to the customer put in a new unit and all is good for 3-6 months then the same thing happens again. Anyone have anyidea on how to get the services to start back up remotely or are we looking at a bigger issue. This will be the 4th Embedded unit at this location.

What version of pfSense? 1.2.1? 1.2.2? 1.2.3?
1.2.3 has only been out for about three months, and it's based on NanoBSD, which is a big step up from the old embedded methodology.
If you haven't yet reflashed these devices to 1.2.3, you'd be best served by doing that first.
The contents of the system log(s) would also help, there may be some info there as to why some services died.

Yes we are running 1.2.3. We were running 1.2.2 and 1.2.1 and 1.2.3 is alot better but we keep having this issue with the system. Here is the Sys Log

I've never seen them on any box I've used, and I have >10 embedded units in the field.

Thats what i was figuring what was wrong but wasnt sure. I have 10 Units out in the field running on Alix hardware along with wireless and they all work great. But this location always seems to be an issue. Could it be an issue with the power resetting? Does anyone know can i recreate the user and or password to get the services started back up?

If you're on nanobsd, you could set the boot slice to the alternate and reboot, and it would be back to normal (but with your config, of course). That's under Diagnostics > NanoBSD
Power loss normally isn't an issue with embedded, as the device is read-only most of the time. Even so, it's rare that a file gets corrupted.
