The most likely cause is that LM is overloaded. Run this script and check the last column (drops) values. If at least one row has a non-zero value it means that a certain system part was unable to process incoming data quick enough. Receive buffer got full and certain messages got dropped.
Code:res = io.readfile('/proc/net/udp')
log(res)
To prevent this scripts must use grp.checkwrite/grp.checkupdate where applicable. Modbus send delta values and KNX filtering tables should be adjusted.
I haven't encountered this issue yet on LMs that are equipped with 2023 firmware.
Thanks for the idea of looking if there was any drop in UDP packets; next time I encounter this bug, I will check it immediately.
