그러나 로컬 SQL Server DB에 동일한 변환을 실행하면 정상적으로 작동합니다.

어떻게 해결해야 합니까?

업데이트 1

TableOutput Step에서 "Commit Size"를 15보다 크게 설정하고 "삽입에 배치 업데이트 사용"을 true로 설정하면 문제가 발생한다는 것을 깨달았습니다.

클라이언트에서 TCP 매개 변수를 수정할 수 있습니다.

REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v KeepAliveTime /t REG_DWORD /d 30000
REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v KeepAliveInterval /t REG_DWORD /d 1000
REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v TcpMaxDataRetransmission /t REG_DWORD /d 10
