[Neo4j] Neo4j: Ver 3.0.4 delete and re-insert label corruption

I deleted the nodes from a label: match(n:clients) delete n; When I attempted to re-load from CSV: using periodic commit 1 LOAD CSV WITH HEADERS FROM 'file:/export/warehouse/tmp/clients_08-31-2016_02-03.txt' as row FIELDTERMINATOR '\t' with row as row where row.ClientsID is not null merge

[Neo4j] neo4j 3.0.1 [Full GC (Allocation Failure)

I am using LOAD CSV to update nodes of an existing label. The label contains 4M existing nodes. The CSV file contains 600k rows; some new, some updates. My Centos 6.x box has 36G of ram. Using the 3.0.1 tuning guide, I have set pagecache to 24G and heap_initial_size/heap_max_size to 8G. Attach
