hazel cast takes 2GB memory

[asgard]

Hi guys:
I have tested hazelcast recently. In my test,I run hazelcast in tomcat
which init in sprint context. I found jVM need more than 2GB memory
as direct memory to run . otherwise, there will be outofmemery error
in log.

java.lang.OutOfMemoryError: Java heap space
at java.nio.HeapByteBuffer.<init>(HeapByteBuffer.java:39)
at java.nio.ByteBuffer.allocate(ByteBuffer.java:312)
at com.hazelcast.nio.DataHolder.<init>(DataHolder.java:29)

65)
at com.hazelcast.nio.ReadHandler.handle(ReadHandler.java:86)
at com.hazelcast.nio.SelectorBase.run(SelectorBase.java:146)

While run the test app is ok. I don't know the reason.
The hazelcast version is 1.9.4.8.Tomcat version is 7.0.25. OS is OSX
10.7.3 and ubuntu server 11.10. OSX with 1.6.0_29 jdk and ubuntu with
1.7.0_03 jdk.

Could some guys help me?

Can you reproduce this issue easily? Does it always happen?

Do you have other hazelcast versions running in your network?

Are you using tcp/ip or multicast join?

Yes,It always happen.
There are only one version hazelcast running in our network.
I'm using tcp/ip join.
