we have a custom board using the ESP32 S2 chip with IDF 5.0.
Our application gathers data via serial port and writes these data to an SD card. Works fine.
On the httpd server we have an endpoint reading this data file repeating every 5 to 10 seconds.
After a while we seeing the following log output

Anybody out there who has seen such before and can give any hint?
Any idea very welcome.
