Randomly get Exception cause: 28 #169

Closed UltimatPronin closed 3 years ago

UltimatPronin commented 3 years ago

Arduino IDE 1.8.13; ESP8266 Arduino Core SDK version 2.7.4; NodeMCU V3;

Randomly get Exception cause: 28. Sometimes after 5-10 minutes, sometimes after 0.5-1.5 hours, sometimes after >12-22 hours.

Your great library is used in big home security sketch, I can't paste it here - it is so big. Firebase used for monitoring (update status data - used 1st object, not stream) & sending commands (used 2nd - stream object). Available heap all time is about 9500-11000 bytes with fragmentation about 2-4%. Now I can't direct access to serial, but exceptions causes & stacks is saved in FS.

Here it is:

Firebase data updates about 1 time per 5-30 seconds. Please, take a look - is problem in library or in used board.

mobizt commented 3 years ago

If you use stream, be careful for the latest version that the memory allocation for the stream payload is unlimited and when the stream data push to the device is too big to device to handle, it may cause out of memory and reset.

For another reason of out of memory, you need to check the free heap for very firebase calls.

If your data at the stream path is too large, reduce it or redesign your database.

The data under the stream path should keep small and should not contains the large log or history data.

UltimatPronin commented 3 years ago

Thank you, I will check. For now, stream is listening the empty patch (not exists for test), but in normal - only very small json is used for stream.

Can you advice, how to avoid it. For now I don't have stream data (for test), but stream is configured for listening patch. Normally I need listen the patch for small json data with command & status for all time.

mobizt commented 3 years ago

Ok I found the bugs in the string utility functions in the library and trying to fix it and will inform you soon.

UltimatPronin commented 3 years ago

Thank you very much!

mobizt commented 3 years ago

The library updated with the bugs fixed. Please try to download via GitHub.

UltimatPronin commented 3 years ago

Thank you for very fast reply! I will try updates now. Looks like problems go off - for now uptime is: >110 hours and everything working perfectly. Great job and amazing library!
