Description

When many GSM SMS messages are sent from the zenon runtime simultaneously, the runtime causes a high CPU load and may stop responding.

Solution

An issue has been addressed in the communication with the GSM SMS modem where processing a large number of GSM SMS messages caused the runtime to stop responding. Now the runtime correctly handles the communication with the GSM SMS modem over the serial port and the runtime no longer stops responding.
