我在 Ubuntu 20.04 LTS 和 Ubuntu 22.04 LTS 上遇到了奇怪的行為（沒有足夠的形容詞來形容）。
這是 IBM Db2 測試伺服器。伺服器在 db2inst1 使用者 ID (UID 1002) 下執行 Db2 服務。伺服器名稱是 srv-db2-teste。
每次我使用 db2inst1 使用者 id 從遠端電腦執行 ascp或 arsync到 srv-db2-teste 伺服器時，成功複製檔案後，在該使用者 id 下執行的所有服務（我說所有服務）都會被終止！無論正在運行什麼進程，所有在 db2inst1 用戶下運行的進程都會停止運行。
Db2 正在端口 50000 上運行，但我測試了其他端口，它仍然會殺死進程。
範例：在遠端電腦中，我執行以下複製命令：
dba@workstation1:~$ scp /db2/files/* db2inst1@srv-db2-teste:/db2/files/
我已經用其他使用者 ID 進行了測試，行為是相同的：除了使用者 root 之外，所有進程都停止運作（不明白為什麼 root 完好無損）。
當進入 db2top（Db2 應用程式）時，遠端 scp 後崩潰，這是錯誤：
SQL1224N The database manager is not able to accept new requests, has
terminated all requests in progress, or has terminated the specified request
because of an error or a forced interrupt. SQLSTATE=55032
(semctl (*id,0,IPC_RMID, (union semun) x)): Invalid argument
db2inst1@srv-db2-teste:~$

我從來沒有見過這樣的事情......非常感謝任何幫助！
