Your device is running out of memory that causes the memory allocation failure and system task will fail to feed the watchdog.

[mobizt]

You should check your code for memory leaks.

This library is memory leaks free.

[mobizt]

After inspected your code, there are incorrectly use of objects that pass to the function by pointer.

You have to follow the examples to avoid dangling pointer issue.

Some objects need to define global as it contains the information or session that used throughout the operation.

[mobizt]

The SMTPSession should be defined globally as it contains TCP and SSL sessions and user data that some of this will be used in the callback.
