Error description
The IBM Systems Director Platform Agent may crash following several network Input/Output (I/O) operation failures. The crash occurs in Standards Based Linux Instrumentation Module (SBLIM) and this impacts the Common Information Model (CIM) provider agent (cimprovagt) which crashes and is unable to restart.
Local fix
There is no usage change that will avoid this issue.
Problem summary
The SBLIM implements the CIM monitoring model. Broadly it is composed of the Gatherer Daemon (gatherd) responsible for gathering metric data and the Repository Daemon (reposd) responsible for centralized data collection. The gatherd is further composed of multiple Metric Retrieval Plugins that do the work of data retrieval. When Director Server Platform Agent starts and encounters several network I/O operation failures, this metric data is gathered by the Gatherer Plugin for IP Protocol Endpoint Metrics. The IPProtocolEndpoint and NetworkPort plugins collect raw network counters from /proc/net/dev. Processing of this data results in a buffer overflow and generates a segmentation fault (segfault). This is reported as a failure in the OSBase_MetricValueProvider module and subsequent segfault in CIM provider agent (cimprovagt). Then the Platform Agent Watchdog daemon will determine that the Gatherer services are not running and will try to restart the Gatherer services. This issue will be fixed in a future release of the product.
Problem conclusion
Temporary fix
