A configuration file that used to work with an older version of ESPHome (2022.6.3) now fails to initialise the MQTT client. From the logs it seems that some memory is exhausted, even though there should be plenty of memory.
Which version of ESPHome has the issue?
2024.4.2
What type of installation are you using?
pip
Which version of Home Assistant has the issue?
N/A
What platform are you using?
ESP32
Board
heltec_wifi_kit_32_v2 (8MB flash)
Component causing the issue
mqtt

No response
Anything in the logs that might be useful for us?

Additional information
Looking at the compile output there should be plenty of memory:
Compiling .pioenvs/co2-sensor/src/main.cpp.o
Linking .pioenvs/co2-sensor/firmware.elf
RAM: [== ] 18.1% (used 59280 bytes from 327680 bytes)
Flash: [===== ] 50.0% (used 1965853 bytes from 3932160 bytes)
Building .pioenvs/co2-sensor/firmware.bin
However, I am using, the web server, BLE server (github://wifwucite/esphome-ble-controller) and MQTT. So some internal buffer seems to overrun. But with the Arduino framework based MQTT client, things used to work fine.
This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.
