Error description
SNMP Agent installed to query PMI data. The agent is installed correctly as Generic Server. With an SNMP Browser we can connect to the agent and query OID. When we Query actual PMI data, CPU spikes to 50 % or more Javacore shows the following, java.io.BufferedReader.readLine(BufferedReader.java:373) ip=0x000007FFFF558EDB/sp=0x11226ED8: com.ibm.ws.pmi.snmp.agent.SNMPAgentServer.interactive(SNMPAgentS erver.java:577) ip=0x21B61F2D/sp=0x11226F10: com.ibm.ws.pmi.snmp.agent.SNMPAgentServer.main(SNMPAgentServer.j ava:528) Native Thread: 16320

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: SNMP agent server consumes high cpu. * **************************************************************** * RECOMMENDATION: * **************************************************************** SNMP agent server is consuming high CPU when it starts successfully. This is due to the internal feature of SNMP which enables interactive mode for the SNMP server. This interactive mode was responsible for high cpu consumption.
Problem conclusion
The code has been modified to fix this. With this fix the SNMP agent server will not go in interactive mode by default and so avoid the high cpu consumption scenario. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.5.
