I have the following problem with lwip-2.1.2
I have implemented the socket API so that it can be used, but in rare cases
the connection is broken.
While investigating the cause, I discovered that the PING response was
interrupted on the way.
Attach the image at that time.

When ping became abnormal, we logged with waireshark.

If you check the log, you can see that the reply is delayed for the request.
For example, a reply of No. 165 is returned for a request of No. 149.
I think Requests and replies are recorded alternately under normal
conditions, but there are some places where this is not the case.
what I can see to understand the problem?
