对于 type=forking 的单元，systemd 状态更改为“正在停用（stop-sigterm）”

我已经编写了一个 systemd 单元来在启动时启动我的应用程序：

cat [email protected]

[Unit]
Description=Start my application
After=local-fs.target network.target

[Service]
WorkingDirectory=/apps/scope
ExecStart=/apps/scope/scripts/startAtBoot.sh
Type=forking
PIDFile=/apps/scope/scripts/startAtBoot.pid
User=%i
#Group=
TimeoutSec=30min

[Install]
WantedBy=multi-user.target

cat /apps/scope/scripts/startAtBoot.sh

#!/bin/bash
#### Description: Startup applications at system reboot
#set -x

(. ~/.bash_profile && /apps/scope/scripts/envMaint.sh start >> /apps/scope/ca/profile-root/runtime/logs/envMaint-`date +\%m\%d`.log 2>&1)&
echo $! > /apps/scope/scripts/startAtBoot.pid

当我启动这项服务时：
[root@alvd17p01 ~]# systemctl start [email protected]

我可以看到父进程和子进程运行了一段时间。

[root@alvd17p01 ~]# systemctl status [email protected]

但几分钟后，设备状态变为停用（stop-sigterm）

[root@alvd17p01 ~]# systemctl status [email protected]

● [email protected] - Start my application
   Loaded: loaded (/etc/systemd/system/[email protected]; disabled; vendor preset: disabled)

我不明白为什么它会失败。我的 envMaint.sh 以状态 0 退出。startAtBoot.pid 有子进程的 pid。

有人能帮我解决我做错的地方吗？
