Openfire 3.10.2 running on Raspbian Jessie hitting 100% CPU

Hi,

I've recently moved my openfire 3.10.2 from a windows 2008R2 to a Raspberry pi 2 (Raspbian Jessie), migration went fine but for some reason, every couple hours java hits 100% CPU use.

root@raspberrypi:/# java -version

java version "1.8.0"

Java(TM) SE Runtime Environment (build 1.8.0-b132)

Java HotSpot(TM) Client VM (build 25.0-b70, mixed mode)

Restarting the service does temporarily correct the issue, but it comes back a few hours after.

Any ideas ?

Sincerly,

N
