Closed as program error.
Error description
The customer has a long-running task which iteratively issues SNMP API calls to collect MIB data. With each iteration, snmp_container storage is orphaned. This occurs until SNMP API calls start failing with SNMP_MGR_RC_OUT_OF_MEMORY (-4). It appears that the containers should be freed by snmpFreeDecodedPDU() calls but aren't because snmpBuildPDU() clears their oid_p and value_p pointers in the VarBinds array.
Local fix
Apply PTF or ++APAR.
