Ever since upgrading to Core FTP Server V2 build 765 I am occasionally seeing "Winsock error 10053" followed by "An established connection was aborted by the software in your host machine" is appearing in the access logs. When this happens, live connections are closed. There are only about 20 connections per day so this is not a high volume SFTP server.
Prior to upgrading to build 765 I was running build 759.
Windows Server 2019 Datacenter running in Azure.
Intel Xeon Platinum 8171M CPU

Re: Winsock error 10053
Build 770 may fix this issue that was introduced in build 761.
