task stop beeing executed

bitz

Hi Forum ,hi Dave,

I'm working on an application for displaying data from an solarcontroller ("epever").

HW is an esp8266.
I have it running, using (in this case) two tasks and mongoose as webserver-lib.
But after a few minutes the tasks stop beeing executed.

Last known RAM conditions seem OK.
Webserver still working and reponds in full.
So i'm a bit lost where to look.
Any hints are very much appreciated.
Thank you !

Here a small code sample, the loop():

void loop() {
  taskManager.runLoop();
  webServer.Mongoose_poll();
  if (restartnow)
  {
    Serial.println("Restart");
    delay(1000);
    ESP.restart();
  }
  loopCount++;

  if (loopCount > 500000)
  {
        //       DBGN("============> MCUsleepTask exec");
    Serial.println(taskManager.checkAvailableSlots(taskDebugData, sizeof taskDebugData)); 
    loopCount = 0;
  }
  notifyWebClients_loop();
}

And one of the tasks:

class cTask : public Executable { // from/for taskmanager
protected:
    unsigned long cycleTimeUs;
    bool taskEnabled = false;
    taskid_t taskID = TASKMGR_INVALIDID;
public:
    void start();
};

class cMCUupdateInfoTask : public cTask {
//private:,
public:
    void start(unsigned long intervalUS) {  
    Serial.print(("start MCUupdateInfoTask: ("));
    Serial.print(intervalUS / 1000000);
    Serial.println("s)");

      taskEnabled = true;
      cycleTimeUs = intervalUS; ///2 secs
      taskID = taskManager.scheduleFixedRate(cycleTimeUs, this, TIME_MICROS);
     }
     
    void exec() override {
               DBGN("============> MCUupdateInfoTask exec");
          mcu.updateMCUinfo();
    }
};
extern cMCUupdateInfoTask MCUupdateInfoTask; ;

Additional Info.

Trying to find a possible memory leak i added quite a few debug messages, among those a display af the attribues available in TimerTask. This time it ran 12h without issues...

Please note that this forum is closed to new entries, and is now readonly, questions about taskmanager - https://github.com/davetcc/TaskManagerIO/discussions

As you can imagine, we have very limited time to look at issues, and we're giving that time to you without charge. Please do provide a standalone sketch that I can run that reproduces the issue on the other forum.

Thanks,
Dave.
