843829Aug 19 2005 — edited Aug 21 2005
Hi,

my java settings:

-server -ms2048M -mx3072 -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC -Xconcurrentio -Dsun.rmi.dgc.client.gcInterval=1800000 -sun.rmi.dgc.server.gcInterval=
1800000 -XX:+AggressiveHeap

my host:
SunOS name 5.9 Generic_117171-07 sun4u sparc SUNW,Sun-Fire-V440 => 4 processors

my problem:
=> this is OK
