Issue/Introduction

Seeing Java agent stopped reporting from AWS Microservices environment.  Earlier it was reporting successfully but now stopped.  I have cleared old logs and restarted applications. 

We do not see any logs generated in CA Wily logs folder.

We are using below command to start Wily agent and the  Application:

nohup java -javaagent:/opt/local/sprcaapp/home/Microservices/wily/Agent.jar -DagentProfile=/opt/local/sprcaapp/home/Microservices/wily/core/config/IntroscopeAgent.profile -Dintroscope.agent.agentName=SPACE -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m -Xmx1024m -Xms1024m -XX:NewSize=512m -XX:MaxNewSize=512m -XX:+HeapDumpOnOutOfMemoryError -XX:+UseParallelGC
