ParNew Allocation Failure

[Nicolas VIAL]

 Hello

I'm trying to use HugePages on a high memory server.
Seems to be working fine except for this king of error messages :

ParNew occured at 2013-02-13 13:34:57.469, took 77ms (Allocation Failure)
eden(-838912) old(+103897)


JVM started with :

d64
XX:+UseCompressedOops
server
Xms30720M
Xmx30720M
XX:+UseLargePages

XX:PermSize=512m
XX:MaxPermSize=512m

XX:NewSize=1024m
XX:MaxNewSize=1024m

XX:InitialCodeCacheSize=256m
XX:ReservedCodeCacheSize=256m

XX:CompileThreshold=1000
XX:+UseParNewGC
XX:+PrintGCDetails

Statistics :

gc(ParNew)[count=20, time=2839], gc(MarkSweepCompact)[count=2, time=472],

cpu[load=0%], disk[rate=75319, used=35%]

Using :
java version "1.7.0_13"
Java(TM) SE Runtime Environment (build 1.7.0_13-b20)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)

Hope i can get some help
Thanks
