The IO error was not always handled by the proper TCP thread, possibly leading to a race condition where two TCP worker threads were touching the same TCP connection object at the same time. Technically the issue also exists for XFR responses, but these are very unlikely to cross protocols. We are still applying the same fix. The issue was introduced in 516a000. This was reported by Thread Sanitizer: ``` 2023-03-10T13:52:59.5959261Z WARNING: ThreadSanitizer: data race (pid=15423) 2023-03-10T13:52:59.5959559Z Read of size 1 at 0x7b040000385c by thread T2
