Tue 29 Mar 2022 10:52:34 AM UTC, original submission:  

Socket connection stalls when other peer is reset and cannot be reached. Connection only resolves by itself after 2 hours.

When socket is closed by force it leaves behind small chunks on the Heap (0-36 bytes),

Running espressif idf framework and unable to read actual lwIP version in release. Using Mongoose 7.4 layer.
