Apr 21st, 2010

Hi

we have installed the MSE 3350 with the lates Context Aware Sup Service from Aeroscout

But the Service still terminated because of unexpected null node message (see below)

Thanks for any help

Ok lets try this:

1. Stop mse (well even if its actually stop, run mse stop).

2. mv /opt/mse/db/linux/server-eng.db /opt/mse/db/linux/server-eng.db.old

3. start mse

Hello Lucien

The Context Aware Sub Service from Aeroscout tries to start the service again and again.

For a few time the Registered-Field changed to "true" and then back to "false"

I just stoped the mse and start it again

/etc/init.d/msed stop

/etc/init.d/msed start

/etc/init.d/msed status

Sub Service Name: aeroscout
Version: 3.2.1 - 04.00.15.12
Description: AeroScout® Location Engine for RSSI and TDOA asset tracking
Registered: true
Active: false

/etc/init.d/msed status

Sub Service Name: aeroscout
Version: 3.2.1 - 04.00.15.12

After upgrade to version 7.

It should be in your MSE:

/opt/mse/locserver/db/linux/server-eng.db
