Reboot when processor processing large files
I get on a stochastic base (mostly after closing the browser, wait 1 hour, open again.. sometimes a reboot of the esp32 (wemos d1 r32) on the moment that we open the index web-page. Just refreshing a page goes most of the times without problems there is no memory leak.... Power is supplied seperately (so no wifi power issue) ESPFreeHeap-126612 ESPMaxAllocHeap-87816 ESPMinFreeHeap-98472 SPIFFS totalBytes 775841 SPIFFS usedBytes 350145
The error trace shows in the middle the SPIFFS_LIB_Create_HTML_Drop_Down(String&, String, String) but the lines above are beyond my understanding
Could someone perhaps take some time to explain what is happening in the error trace lines above SPIFFS_LIB_Create_HTML_Drop_Down(String&, String, String) and hopefully give an understanding why this error is happening and results in a reboot?
My feeling is telling: it has to do with the stack, but i do not understand Why.... i already increased the available memory but that did not gave any improvement.
so in the web-page , i have the text $DROP_DOWN_FILE_DOWNLOAD$ ( characters are updated due to css characters^_^) to identify for the processor the location of the created html drop down with file-names ....
