Severity: 3-Major


Upon querying a sysTmmStat* SNMP OID (for example, sysTmmStatTmUsageRatio5s), you find your SNMP client returns an error message similar to the following example: No Such Instance currently exists at this OID The very next time you query that same SNMP OID (or any other sysTmmStat* SNMP OID), you find they all work as expected and return the correct result.


All sysTmmStat* SNMP OIDs do not work until one of them is queried at least once, and the query is allowed to fail. After that, all sysTmmStat* SNMP OIDs work as expected.


This issue occurs after restarting only the mcpd daemon, i.e., running bigstart restart mcpd.


Restart all services together, i.e., running the command: bigstart restart. Should the mcpd daemon happen to be restarted on its own, you can simply ignore the error message and allow your SNMP polling station to fail a single polling cycle. If you want to ensure that this issue does not occur, for example, so that your SNMP polling station does not generate unnecessary alarms, do not restart the mcpd daemon on its own, but rather restart all services together by running the following command: bigstart restart
