Error description
When clearing a map with eXtremeMemory enabled, it's possible that not all data will be cleared from the associated global index. This could cause subsequent queries on the MapGlobalIndex API to return incorrect data. In particular the findPartitions method on MapGlobalIndex may return partitions which don't actually contain data matching the indexed attribute. If the customer is using the results of findPartitions to run map agents, their implementation should be tolerant of the agent running on partitions which no longer container entries matching the provided attributes.
Local fix
