有人知道如何解决这个问题吗?

Does anyone know how to solve this problem?

推荐答案

所以重要的部分是:

lotus.domino.AgentLoader.addAttachment(Unknown Source)

AgentLoader.addAttachment是在首次开始执行代理程序时运行的方法.它的作用是检查代理程序中是否包含代理程序中的任何JAR，然后下载(如果在客户端上)，并将它们分离到系统中，然后再将其加载到JVM中.

AgentLoader.addAttachment is a method that runs when your agent is first starting to be executed. What it does is checks your agent for any JARs contained within the agent and downloads (if on client) and detaches them to the system before loading them into the JVM.

您的代理完成后，将清理它们.因此，每次代理运行时，都必须执行此步骤.

When your agent completes it cleans these up. So every time the agent runs it has to do this step.

由于某些原因，可能会发生此错误.

This error can occur for a few reasons.

原因1 :(主要的)

网络和处理上都存在开销，无法将负载/罐子分离到系统中.如果您负担很重，则系统可能没有足够的内存来完成操作.

There is overhead both in network and processing to detach load/jars to the system. If you are under a heavy load it is possible that the system does not have enough memory to complete the action.

原因2:

某些第三方API不能以这种方式工作.例如，我看到的Google API会以这种方式失败.

Some third party APIs will not work in this fashion. Google API for example I have seen fail in this way.

原因3:

V8.0(SPR KPAL6YWRN9)中与Web服务有关的内存泄漏.此后已解决.

There was a memory leak in V8.0 (SPR KPAL6YWRN9) in relation to web services. This has since been fixed.

如何解决此问题:

删除代理中包含的所有jar，并将其放入jvm/lib/ext文件夹中.您将需要重新启动Domino/Notes.然后，jar将仅由JVM加载一次.

Remove any jars you have contained in your agent and drop them into the jvm/lib/ext folder. You will need to restart Domino/Notes. The jars will then be loaded by the JVM only once.

如果此时仍然出现错误，则很可能是另一个Java代理在其自身之后没有正确进行清理.

If you are still getting the error at that point, then is more likely another Java agent is not cleaning up correctly after itself.
