Issue:
At some unpredictable point in time, my application suddenly start
consuming a lot of memory, leading to memory issues.
It's so strange. My application in general terms turns an XML into a graph.
There are several files that represent a particular version, for each one I
read the nodes and save as vertices. Hierarchy and explicitly defined
relationships are stored as edges. It starts ok, with a reasonable
processing time. Let's say that it takes from 5 to 15 minutes to process a
file.
Then the problem appears without no apparent reason. I file takes 1,5 hours
to process and the next throws Out of Memory after 3 or 4 hours. Right now
I have one which is running for more than two hours(why?).
I made almost every tuning described at the site, apart from defining the
vertex classes before hand. I don't want to control the schema, so I didn't
go through this point.
I can share my application if you want, but it's not open so I can't post
in the group. If you have a Bitbucket it would be easier to share.
OrientDB version: 2.0.5
Enviromnent: Amazon EC2, m3 large, with Amazon AMI
Software configuration: tried plocal and remote, both throws Out of Memory.
Apart from the server script, I have increased the socket timeout.
