Description (partial)

cfmd process abnormally restarts after querying SLA PM-MIB OIDs.
Further restarts may be seen if the same SNMP query is repeated before the data has updated (the SLA data is persistent over cfmd restarts; if the data hasn't been overwritten by new probe data, the same query will result in the same process restart being seen).

This issue is seen if multiple metrics are configured for a probe, but the first metric does not have valid data for a given bucket.
