memory-usage

Relevant part of the start up line: java -server -Xms10G -Xmx10G -XX:PermSize=1G -XX:MaxPermSize=1G

This instance ended up taking up 16GB of memory and 10GB of swap before killing the server.

Any ideas on what could cause that?

This is the only major application running on a RedHat system with 16GB RAM and 10GB swap.
