Ubiquiti LTE device show corrupt serial numbers

Thanks for looking at this and with the update installed, the repeated poling message have stopped and the record no longer shows a serial number.

Thanks everyone

It seems that this device didn't respond to the serial (mac address) query this poll :

Though it had a garbage serial in the database already from the previous poll:

  [serial]                    => string(8; UTF-8) "ô?¿i+"

You should re-run the poll a couple of times to check for these parts and see what the device is returning for afLTUMac.0

./poller.php -h <device_id> -m os -d

Or you can manually run the snmpget command a few times and see what it returns over time (might only change infrequently, or every poll).

This definitely looks like a vendor bug that Ubnt need to fix.

adam.

Your device seems have an memory leak and return random data on requests serial Oids.

I added checks for valid serials for this os.
Issue should be fixed in r12011.
