我在 Ubuntu 20.04 LTS 和 Ubuntu 22.04 LTS 上遇到了一种奇怪的奇怪行为（没有足够的形容词来形容）。
这是 IBM Db2 测试服务器。该服务器在 db2inst1 用户 ID（UID 1002）下运行 Db2 服务。服务器名称为 srv-db2-teste。
每次我使用 db2inst1 用户 ID 从远程计算机运行 ascp或 arsync到 srv-db2-teste 服务器时，在成功复制文件后，在该用户 ID 下运行的所有服务（我说的是所有服务）都会被终止！无论正在运行什么进程，在 db2inst1 用户下运行的所有进程都会停止。
Db2 在端口 50000 上运行，但我已经测试了其他端口，它仍然会终止进程。
例如：进入远程机器，我执行此复制命令：
dba@workstation1:~$ scp /db2/files/* db2inst1@srv-db2-teste:/db2/files/
我已经用其他用户 ID 进行了测试，其行为是一样的：除用户 root 之外的所有进程都关闭（不明白为什么 root 完好无损）。
当进入 db2top（Db2 应用程序）进行远程 scp 后崩溃时，出现以下错误：
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:~$

我从来没有见过这样的事情......非常感谢任何帮助！
