Hello.
I am experiencing really strange problem here. When I start jboss, some entites are
pre-loaded into cache. Then, if I load more and more entities in there, suddenly cache
become empty and start all over - this causes dbs traffic of course.
On my local pc, if there are some nodes in the cache (sometimes 275, sometimes 900 it
depends which operation I run), then cache gets suddenly clean, and when operation finish,
the number of nodes in cache is 10 - and its only directories.
On production server this process repeats and repeats.
Could somebody help me to keep the nodes inside the cache bit longer??
Here is my configuration
