Wireshark logs show sometimes a lot of TCP retransmissions #2602

Type of issue

Current Behavior

Observing wireshark logs when a .NET client or server is involved, sometimes contains a lot of TCP retransmissions.

It doesn't cause functional issues but seems incorrect and the root cause is yet unknown.

Recently I noticed again these bursts of retransmissions in a Wireshark log. This behavior may have to do with large chunks that the .NET stack defaults to (65535). Test with different defaults (8k) should show if this is reproducible.
