期望的结果

What do you expected from the above steps？

实际运行的结果

实际运行结果，最好有详细的日志，异常栈。尽量贴文本。

在 issue里搜下相关的，参考下

hhzhong · 2020-09-17T03:03:54Z

搜过，有个类似的internal error，但没看到解决办法，可以帮排查下吗？

hengyunabc · 2020-09-17T03:25:27Z

#1141

hengyunabc · 2020-09-24T12:46:16Z

@hhzhong 可以测试下这个版本： #1526 (comment) ，解压，cd进目录启动。

hengyunabc · 2020-09-27T15:36:39Z

试下最新的 3.4.3 版本，应该已经修复了。

kylixs · 2020-09-30T12:56:28Z

这个错误是什么问题？没有任何信息

@kowhi 最好能提供可重现的demo，参考 #1141 ，看有没有其它的 java agent。

zhumengguang · 2023-03-31T08:20:25Z

@hengyunabc 我也遇到了这样的问题，系统存在skywalking-agent监控，这个如何解决呢？
