Hi,
I started working with Splunk a couple of months ago, and we are currently using Monitoring of Java Virtual Machines with the JMX app to monitor the health of JVM. Lately, I noted an issue where the app stopped working and getting data from JVM after the server CPU spiked to 100%. I tried to restart Splunk on the server and checking logs; I have the following error:
2023-07-04 08:18:46 ERROR Logger=jmx://XXXXX host=XXXXX, jmxServiceURL=, jmxport=XXX, jvmDescription=XXXX, processID=0,stanza=jmx://XXXXX,systemErrorMessage="Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.io.EOFException]"
It was working before the CPU issue, and the server had no changes. I double-checked all configurations, and tried restarting Splunk and reinstalling the app, but it always returned the same error. Does anyone have a clue?
