Wifi heap allocation failure.

[snahmad75]

Hi,


Kindly see below. I am getting these heap allocation errors time to time.
I am using Wifi with external ram. I access my my http web server mongoose using SD card.
May be it is due to slow SD card access. how can increase WIFI buffer using menuconfig.
Once restart esp32 firmware. all starts working again.

Can Anyone tell me C/C++ code where this log is generating from?

CONFIG_WIFI_LWIP_ALLOCATION_FROM_SPIRAM_FIRST=y make it work.
