I have Neo4J Enterprise set up on a single node. The following are the
basic stats.
5 Mn nodes.
45 Mn properties
3.7 Mn relationships.
10 GB disk usage of about 50 GB disk total.
8GB RAM
What we are observing is that everyday we end up bouncing the Neo4J
service (stop & start) because the service becomes extremely sluggish
to respond after being up for few hours. It becomes so slow that even
the web-admin console does not come up when invoked in the browser.
The surprising part is that there is very little load on the server,
there is only about 100 queries to the server during the day and they
are simple look up queries since we are in prototype mode right now.
I wonder if anyone else experiences this. Also, what is the right way
to debug this. Is there a way Neo4J provides info. on the heap usage
and other performance stats or should I just use standard ways to
monitor the Java-process?

Can you add gc logging
And perhaps generate a heap dump with jmap and a thread dump with jstack
As well as send along the messages.log

Also can you check the system status with top and iostat?
