customer application (self written app server) reproducably dumps core when run with 1.4.2 server vm in 32bit and also 64bit mode.

System is running Solaris 8, latest rec. patch cluster applied and also j2se patch cluster.

The VM dumps in the following cases:

1) -server -d64/-d32 -Xms2048m -Xmx2048m -Xss6m -XX:+AggressiveHeap ...
2) -server -d64/-d32 -Xms2048m -Xmx2048m -Xss6m -XX:-DisableExplicitGC -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+UseAdaptiveSizePolicy

Only when run in -client mode the application runs fine.

For all crashes the Hotspot Error ID and the shown function name are the same.


java -server -d64 -Xms2048m -Xmx2048m -Xss6m -XX:-DisableExplicitGC -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+UseAdaptiveSizePolicy -Xloggc:/tmp/gclog.out -Djava.rmi.server.hostname=xxx -classpath ....
