我在更新 SLES 12.5 服务器时遇到问题。由于另一个 zypper 进程已经在运行，Zypper 可能无法工作：
# zypper lu
System management is locked by the application with pid 25074 (zypper).
Close this application before trying again.
如果我再试一次，PID 就会改变：
# zypper lu
System management is locked by the application with pid 27117(zypper).
Close this application before trying again.
如果我尝试杀死 27117，它不起作用，因为它不再存在：
# kill 27117
bash: kill: (27117) - No such process
PID 存储在
# cat /var/run/zypp.pid
31776
同样，如果我重复该命令，我会得到不同的 PID：
# cat /var/run/zypp.pid
525
这是我发出命令时 zypper.log 的样子zypper lu：

知道这里会发生什么吗？我过去通过重新启动解决了这个问题，但我想找到一个更好的、不那么激烈的解决方案。
