I experienced that on Solaris when I'd placed the db on a filesystem that
didn't support memory mapped I/o such as NFS

There is no issue - just user mis-understanding of how it works - or doesn't if
ones database is located on an NFS file-system. A little documentation on the
necessary preconditio
ris, and indeed
whether that would further help performance, or does it just reduce the heap
demand?

A colleague has speculated that it maybe related to permissions. Im on a
shared solaris box with no setuid access - can anyone elaborate on whether some
specific access rights are required to use memory mapped IO?

Is there some record within the Neo4J database or its indexing that retains
knowledge of the location where it was created? Only I tried coping a neo4j
database from a Windows drive to a Unix file system and started a Unix neo4j
application pointing to it and while it connected apparently ok, w
might be fixed in the new milestone release.
My questions regarding what actual effect using the
EmbeddedReadOnlyGraphDatabase is still relevant however...?

Unable to access the data tab using IE version 7. Tried using the Eclipse built
in browser and it momentarily switches to the data tab but then it disappears
again.
What are the supported browser platforms?

The above exception is thrown from the call stack indicated below while
traversing a neo4j graph using the EmbedesReadOnly database. Using 1.4M04.
The application is running with 1gb of heap with defaulting all other

I too am experiencing similar problems - possibly worse than you're seeing as I
am using a very modestly provisioned windows m/c (1.5Gb ram, setting max heap
to 1Gb, oldish processor).
I found that using the BatchInserter for loading nodes the heap grew and grew
until when it was exhausted ever
.
Any further suggestions folks?

I have a simple program that uses the BatchInserter to load rows from a SQL
database and am running it on a modestly configured Windows machine with 2GB of
RAM and setting the max heap to 500M.
Initially it was running out of memory quite soon so I introduced a flush after
every 5000 nodes and
m by my own ‘id’, so it is the best option to ‘simply’ iterate thru’ the
