We are running Windows 2003 with 2 GB Ram and Openfire version 3.6.4. Recently our Java Memory, under the Openfire Admin Console, started to spike up to 95% and higher making Spark completely unusable. We upped the amount of Java Memory several times but after a few days found ourselves in the same predicament. Currently we have our Java Memory set at 512MB. How can we stop our Java Memory from running away causing Spark to become unusable. We currently have around 300 users using Openfire and Spark. Thanks in advance for any help provided.
