What is the expected behavior?

Previously provisioned WiFi connection attempt results in ""os_memblock_get failed.." in Monitor log. I do not see this with 5.3.1 or earlier idf versions. Also, free heap is 7K less for the same application compiled with 5.4 compared to 5.3.1 idf version. Not sure the two are related but the warning is a concern on its own.

The app also uses Nimble BLE in the central mode (normal boot mode) and in peripheral mode during WiFi provisioning.

What is the actual behavior?

os_memblock_get failed (size 4) warning seen once to repeated 4 times during boot up wifi connection.

Steps to reproduce.

Compile applicaiton with 5.4, program and boot device.
