Hi,
After storing a while data (about 80.000 nodes) into an CR, an out of memory
error occurred:

If I add more properties or change the binary data mime type for full text
indexing, then I'll get the error sooner.
If I quit the application and restart it, it works again for a while. It seems
to me, that lucene is stacking up memory.
How can I handle that situation?
Kindly regards,
Robert Seidel
