如标题所述。之后，wrapper 无法启动另一个 JVM，我的 mule 服务停止了。和这方面的线索？
服务器上有一点负载，但负载不应该太多。
以下是相关日志：
发送数据包 PING : ok
读取数据包 PING : ok
从 JVM 得到 ping 响应

JVM 出现挂起：等待来自 JVM 的信号超时。
JVM 没有按请求退出，终止了在端口 32002 上侦听的服务器
。在启动另一个 JVM 之前等待 5 秒。
信号被困。详细信息：
信号编号=17 (SIGCHLD)，source="unknown"
收到 SIGCHLD，检查 JVM 进程状态。
JVM 响应信号 SIGKILL (9) 退出。
JVM 进程以代码 1 退出，但包装器退出代码已经为 1。
无法启动 JVM
<--包装器已停止
这是我使用以下命令重新启动 mule 时的日志：mule start。
