jvm crash with jdk 8 and AD agent ver 4.3.2.2

[nbommu]

Hello,

we have noticed  jvm crashes in prod, when we look for stack trace we found AD related classes, no issues on other apps servers where AppDynamic agent is not installed,   can some one help us to figure out the issue?

JAVA: jdk_1_8_0_112

Tomcat: 7.0.56

AD java agent: 4.3.2.2

Hi Niranjan,

Crashes like this are very rare, so my recommendation is to open a Support ticket at https://help.appdynamics.com/hc/en-us/requests/new

Please provide the stack trace below, and also upload the agent logs and ideally the java core dump file to the case so that the Support team can determine what went wrong.

Regards,

Brian Wheeldon
