Crashes / exception with atomlite

[mm-uiflow]

Hey guys, i have used "try" around my i2c loop and mqtt to get the error and try to recover from it. how ever struggeling to fix it( i heard from an alternative mqtt library but i wanted to know if you guys have another idea)
Here you see my grafana graph. Loop gets increased after every "readvalues loop function" (mqtt )

After these about 3000 loops it resets.

Here is the flow:

And this( bottom of the read values function) :

i get -104 mqtt exception and -110. i dont get to except it and try to stop the mqtt, wait a sec and start again. The wifi signal is good and its 1 m to the AP on this Atom ( not like in the other thread)

i found out when i set mqtt's QoS to 0. i have loops over 20k and higher. So no exceptions anymore ( it was memory alloc exception before).

i want to use QoS 1. QoS 1 sends a message with a packet id see code below.
What is the max interger value of micropython / uiflow? It seems like its crashing near the packetid value "65000"

it fixed my problem with the crashes, but now i have no QoS 1
