Make sure your tx is not too big for your memory, according to your messages
log your JVM only runs with a few megabytes of memory.
Try to limit your tx-size to 10k or 20k elements (nodes and rels) restarting
the tx after calling
if (count++ == 10000) {
tx.success(); tx.close();
tx = db.beginTx();
count = 0;
}
Cheers,
Michael
