6 years ago Ok, I can see where the way this is working at the moment is most likely causing the Heap to run out of memory which is causing the exception 28 and reboots. I'm guessing different boards have differing amounts of RAM which is probably why some are experiencing it earlier than others. In my case if I get up 2 groups and 4 scenes I end up with exception 28 when a client polls to retrieve the device config. When it get to add the scenes to the response, it creates the Json response, taking up heap and it then creates a char buffer version of the response in sendJson(). I think there are a couple of approaches we can use to resolve this. 1) Look in to streaming the Json response instead of sending the char buffer. Not sure this will solve the problem if internally the approach is the same, but worth investigating. 2) move away totally from using the heap to store group and scene info. Currently this info is stored on the heap in the following arrays
LightGroup lightGroups[16] = {nullptr, }; LightGroup lightScenes[16] = {nullptr, };
My mods were simply saving changes to SPIFFS files and reloading from these files on start up. I will look into updating the code so that these arrays are no longer used and SPIFFS is read to recover the info. This will free up some of the heap atleast.

6 years ago Hi all,
I've got the same problem at exactly the same moment as described by @rmuike . (However I'm using an Adafruit Feather HUZZAH ESP8266).
I also found out how to generate a stacktrace using EspExceptionDecoder. However in my stacktrace it references to line 491 of SSDP.cpp, so I'm not sure whether it is a memory issue as described above (@Quanghoster).
Since I have no experience in C++, I can not confirm this, but hope that someone has extra information to solve this issue.
Please find my stacktrace attached:

6 years ago Looks like a few memory leaks in scenePutHandler and sceneCreationHandler (LightService.cpp), I changed:
char* json = aJson.print(lightScenes[sceneIndex]->getSceneJson(true));
f.print(json);to
aJsonObject *json_object = lightScenes[sceneIndex]->getSceneJson(true);
char* json = aJson.print(json_object);
f.print(json);
f.close();
free(json);
aJson.deleteItem(json_object);I've also been formatting the SPIFFS each time I run it.
SPIFFS.format();
after
SPIFFS.begin();
in LightService.cpp
This work for anyone else?

6 years ago Hi all! I have the same problem. With the solution of xifer I got rid of the exception, but I was not able to save a Room. Any update? Thanks!
