5 years ago 你好，这个升级xxl-rpc到 1.4.1，或者升级 XXL-JOB到最新版本可以解决。低版本的一个小概率问题。

Please answer some questions before submitting your issue. Thanks!
Which version of XXL-JOB do you using?
2.0.2
今天发现admin怎么都执行不起来，打开admin日志一看： com.xxl.rpc.util.XxlRpcException: java.lang.IllegalStateException: failed to create a child event loop at com.xxl.rpc.remoting.invoker.reference.XxlRpcReferenceBean$1.invoke(XxlRpcReferenceBean.java:227) at com.sun.proxy.$Proxy129.run(Unknown Source) at com.xxl.job.admin.core.trigger.XxlJobTrigger.runExecutor(XxlJobTrigger.java:196) at com.xxl.job.admin.core.trigger.XxlJobTrigger.processTrigger(XxlJobTrigger.java:149) at com.xxl.job.admin.core.trigger.XxlJobTrigger.trigger(XxlJobTrigger.java:74) at com.xxl.job.admin.core.thread.JobTriggerPoolHelper$3.run(JobTriggerPoolHelper.java:77) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.IllegalStateException: failed to create a child event loop at io.netty.util.concurrent.MultithreadEventExecutorGroup.(MultithreadEventExecutorGroup.java:88)
