PiBridge failure after some time working

[Projektraum]

Hello,
During our last tests using a Core3+DIO+DO+AIO modules, we noticed that they all boot fine,
work for some time, and suddenly we have a communication problem between the modules.

We noticed that the Power LED from all modules goes always ON. According to the documentation,
this means that there is something wrong with the PiBridge, but why after a reboot it works again
(sometimes for even hours until stops again)?

Could it be really a hardware problem or maybe a software problem, which is causing the PiBridge
communication to fail? We are using currently Python3 with RevPiModIO2.

Is there somewhere a details log about the PiBridge where we can check from where comes this failure?

Many thanks in advance,
Nathan

Not even a suggestion where I can check if there was
an error or something related to the PiBridge? Is there somewhere
on the system a log file regarding this communication between the modules?

sudo apt upgrade
sudo reboot

and update the firmware of you modules?
