Hi David,
I increased the memory settings in neo4j-wrapper.conf as below
# Initial Java Heap Size (in MB)
wrapper.java.initmemory=30
# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=1024
However the same problem is still happening. I attach the thread dump to this
mail. I appreciate it if you tell me what's wrong based on the thread dump.
Thank you!

Hi Andrew,
Good to hear that you got the logging sorted out.
Regarding the actual issues, it sounds like you're describing two different
things. One is that you index ontology nodes in one global index and
therefore run into conflicts. The other is that the upload appears to stall
for some reason.
Regarding the global index, did you intend to design the system that way,
or do you really want a separate index for each ontology? It sounds like
that would be reasonable.
As for the stalled upload, a thread dump during the slow processing would
be most helpful. On a Linux system, you can capture that by doing kill -3
<pid> on the Java process. It should then go to console.log.
Thanks,
David
