    Hello,

    I am having a very annoying problem. I have programmed a PFC200 with codesys 3.5 for my home automation. It controls my lights and my heating (with the HVAC Building & Process Automation SL library) (and a couple of energy meters).
    I also have a visualisation for the heating.
    When I start the PLC everything is fine. 50% CPU load and 17% memory use. The problem is that every day the memory use goes up by about 5-10% (give or take) until it is completely full and the PLC stops working. Really enoying because if this happens at night it means no more lights an no heating.

    The only thing that works is disconnecting power to the PLC and reconnecting it. Everything starts from the beginning.

    Doing a soft reset (reboot via SSH) works only for a very short time and the process of filling the memory goes a lot faster.

    could you report this to CODESYS Store-> my question bug report?
    Add project archive and steps to repeat please.
