Zigbee gateway integration

[Zen]

Hi everyone,
after getting the newest RS232 ZigBee gateway, we are getting in trouble with some errors and we can't pair anymore devices.
At the first start, we were able to pair 2 Wiser Drayton Valve Actuator without any trouble, then we have restarted the machine. Devices were not responding so we try to re-pair back the 2 Wiser VA, but no way to do it.
So i started reading the logs and i found some mistakes, seems like the gateway is restarting contiuosly. 
Ill' post the log here:

Code:

I have also tryed to uninstall/reinstall/restart LM5 at least 5 time with no differences.
I'm running the latest ZB app with LM5 Lite (i.MX6) SW: 20220922

Updating the last post, after some restarts, we were able to pair again the two VA and another 2 temperature probe.
But after some minutes, here we go again with some new errors on the log that i'll attach the file.
