Howdy,
We've started experiencing reasonably consistent java.lang.OutOfMemoryError
exceptions.
We're using neo4j-community-1.4.M04-windows.zip, running on Windows 7 x64 for
development + Windows Azure for production.
Graph access is exclusively via REST. We perform basic CRUD operations and
Gremlin queries.
The server spins up like so:
12/08/11 2:39:43 PM org.neo4j.server.NeoServerWithEmbeddedWebServer INFO:

12/08/11 2:39:50 PM org.neo4j.server.NeoServerWithEmbeddedWebServer INFO:
Server started on [http://192.168.10.151:5102/]
Then, after a relatively small number of queries (sub 500? still confirming
more details), we get this:
Exception in thread "RMI RenewClean-[192.168.10.151:31174]"
java.lang.OutOfMemoryError: PermGen space
Exception in thread "Statistics Gatherer" java.lang.OutOfMemoryError:
PermGen space
Java.exe is still running, and consuming around 180MB of RAM (with another 3GB
of physical memory still available on the system). REST API returns 500s and
the WebAdmin is unavailable.
My questions:
1) Is this just that we've got a configuration setting wrong? In my very
limited knowledge of Java, I know we can reconfigure the size, but this seems
to indicate a potentially larger issue.
2) What should I do to gather more information to help diagnose this?
