接收邮件时执行的Java崩溃 我想做什么

我想在收到电子邮件时运行jar。 我编写了如下配置文件

/etc/别名

mail: mailuser,| "/bin/bash /tmp/mailtest/mailtrigger.sh"

/tmp/mailtest/mailtrigger.sh

#/bin/bash
echo start>>/tmp/mailtest/stdout.log
java-jar/tmp/mailtest/example.jar
echo end>>/tmp/mailtest/stdout.log

从CLI运行效果很好 从CLI运行

bash-mailtrigger.sh

可以正常工作

/tmp/mailtest/stdout.log

start
success
end

start
end

从电子邮件运行时崩溃 当命令

mail-s测试mail@example.local

执行后，它将变为以下内容

/tmp/mailtest/stdout.log

start
success
end

start
end

电子邮件已正确接收，sh正在运行。但是，将输出以下错误文件

记忆似乎足够了 我认为这已经足够了，因为即使从CLI执行，内存也不不足。 我将写以下内容以防万一

vmstat

procs -----------memory---------- ---swap-- -----io---- -system-- ------cpu-----
 r  b   swpd   free   buff  cache   si   so    bi    bo   in   cs us sy id wa st
 1  0  50176 807536      0 391192    0    0     1     2   39   35  4  3 93  0  0

不仅jar，java版本也不起作用 按如下方式重写sh文件也会崩溃

/tmp/mailtest/mailtrigger.sh

#/bin/bash
echo start>>/tmp/mailtest/stdout.log
#java-jar/tmp/mailtest/example.jar
java版本
echo end>>/tmp/mailtest/stdout.log

当然，它会从CLI中成功

 java -version
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_212-b04)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.212-b04, mixed mode)

其他资料 如果没有足够的信息，我很抱歉。 我将补充必要的信息

有麻烦了。帮助我。请。

原因是塞利努克斯。 我临时将SELINUX更改为Permissive，结果成功。 多谢各位
