Might be worth giving it more memory ? both perm space and heap, its a
bit hard to see how much you have given it so far, but under load or
with a large index space (thats number of terms not number of items) I
would not be surprised to give the JVM 1G. (YMMV)
How much memory have you given it ?

Hi,
Out of interest, what was the nature of the crash ?
Did the JVM just freeze or was there a traceback?

Hi,
I am a new jackrabbit user. We are using this repository for
storing our
application's data. In doing so we are facing scalability issues.
Our application has a huge number of properties, around 1 million.
These
properties are distributed in versionable jackrabbit nodes, each
node
having
around 50 properties and 15 children nodes. Each property has a
unique 50
character long value. We use MySql for persistence.
While creating the tree our application crashed. The indexes grew
to more
that 4.5 GB. Later when we tried to remove the root node, the
indexes grew
to 15 GB and the application crashed again. As we plan to use search
functionality, we cannot disable indexes.
The actual data is around 100 MB. As jackrabbit is a content
store, I am
sure it can support this data size. Please provide some pointers
suggestion
to fix the problem.
Regards
aasoj
