ERROR: Rolling file C:\JavaAgent\App**

[CommunityUser]

Hi,

I am getting the above error and the application start after 15 minutes. Whereas when I remove the appdynamic's -javaagent argument from the application it starts normally. 

This is a unique problem because sometime the error is there and sometime it does not appear. But when it appreas it even stops my application(to be monitored) from starting for a very long time.

When I change the javaagent then again one time it starts correctly but then there is no guarantee that this will work another time.

Hi Nagendra,

Can you please send the following to debug further:

- Provide 5-10 thread dumps when delay in server startup issue happens

- zipped version of logs under <agent_install_dir>/logs path

- complete error console logs

Once you collect all above logs can you add the following jvm arg in addition to -javaagent entry in server startup script and 

see if jvm/webapp starts bit faster after jvm restart:

-Dappdynamics.bciengine.class.lookahead=*​

The error occurs in my application window. But they are not in the log files of agent not the server. 

Due to security reason I cannot provide the log files of my application. 

Please let me know if you need more information.

Hi Nagendra,

If you have concerns you can send the logs requested in a private message, hope that is fine with you.

Also did you checked the behavior with lookahead jvm arg and restart jvm as suggested earlier?

We are testing in a test environment. And our log files are pretty confidential. I can just say that the error which is appered in in the scree shot above. 

Please let me know what is causing it?

And this argument: -Dappdynamics.bciengine.class.lookahead=*​  does not help the application. 

I have seen in bytecodetransformer log file. It is reading all my classes name, saying got successfully verified, but this really slows my application down. Please suggest. My applicaton has millions of classes.

Hi Nagendra,

As per discussion in your help ticket # 28614 , Can you leave node-name element in controller-info.xml blank if you want to use same agent_dir but want to name each JVM instance using -javaagent arg a unique node dynamically and see how it goes after server restart with following -D jvm args in place:

-Dappdynamics.agent.reuse.nodeName=true -Dappdynamics.agent.auto.node.prefix=myPrefix

Also regarding the delay in agent startup Can you please change the jvm lookahead arg as below if you are using older agent version say pre-3.8.3 version: 

 -Dappdynamics.bciengine.class.lookahead=!*  (note the addition of symbol in the new arg)

Let us know if that information helps. 

Regards,

Arun

Hi Arun, 
I am getting this error after adding that -D jvm agrgs

Here are the agent log files:

Hi Nagendra,

Somehow the tier name is also left blank i guess under C:\JavaAgent\AppServerAgent3921\conf\controller-info.xml and also it looks the node related JVM args are not picking up under jvm startup settings file in whcih you have added -javaagent:"C:\JavaAgent\AppServerAgent3921\javaagent.jar" entry, Can you please and correct and restart JVM if issue still persists please provide the controller-info.xml at C:\JavaAgent\AppServerAgent3921\conf path and jvm startup settings in addition to following command output:

cmd> JPS -v

JPS is command from JDK_HOME/bin path that list output like ps -ef | grep "java" in linux for windows
