What is the expected behavior?

Read and write on FatFs filesystem without any problem.

What is the actual behavior?

Suddenly sometimes the storage overflows and there is no more space in that. Also, there are sometimes some corrupted files written in it with format XXXXXXX.XXX which X is 0xff in binary. Plus, esp_vfs_fat_info fuction returns the out_free_bytes 0 byte.

Steps to reproduce.

It’s suddenly and does not have clear behavior, but it happens when operation on filesystem is much more than usual, such as removing and recreating a file.
