CPE already in session

Hey there,

On my path to get 1.2.7 working, I got the logs below on the cwmp service.

CPE already in session

After that, I cant get any information from the device, and after rebooting, the problem persists.
Is there anything that I can do? What`s the reason for that?

Note: Just to clarify, the device sends info to the ACS, but the server responds with the log above.

It was possible to replicate the problem, by sending REBOOT to the device through the ACS UI Interface.

on Debian:

journalctrl -f | grep cwmp

that and genieacs-cwmp log file located on /var/log/genieacs might give you a clue of what’s wrong.

I had that issue before and I managed to pinpoint the problem: it was the extension which in turn used an external web service to access a database which manifest specially during blackouts when dozens or even hundreds of CPE were trying to connect to ACS at the same time.

Modified provision to tag each CPE on boot even and made a group of bash script running in background to call them one by one to avoid the bottle neck. And while it is still a work in progress at the time I’m writing this, we made a switch to text file located on filesystem (JSON files, just to honor the K.I.S.S. rule) instead of a Rest API call and so far seems to be working a lot faster and just fine.

sry about the late reply.

hello. Sorry to use the same post, but i had same issue of “CPE already in session” on one CPE on my lab, when i try to gpv some parameter via genie GUI. Other cpe same model same fw does not have this issue
