I have the vague recollection that not until the kernel that was part of RHEL 4 did multi-CPU processing become viable. But maybe my recollection is bad. We have been using RHEL 4 and higher on multiprocessor machines with no issues. I am running Fedora 6 on a dual-CPU machine with no issues.
Also, you never said which JVM you are using.
Any possibility you could upgrade to a more current release?

I have a server with 2 cpu XEON(3GHz) and 4GB in RAM
I have installed Fedora Core 3 and JBOSS 4.0.2
JBOSS is initialized with next options:
/java -server -Xms1024m -Xmx2560m
-Dprogram.name=run.sh -Dcom.sun.management.jmxremote -Djava.endorsed.dirs=/opt/jboss-4.0.2/lib/endorsed -classpath /opt/jboss-4.0.2/bin/run.jar:/opt/java//lib/tools.jar org.jboss.Main
When I start Linux with a simple kernel(only sees 1 cpu) the processes I run are ok and have no problem, but when I start Linux with a kernel smp(sees the 2 cpu), the time these processes late is too long and never end.
I think it's a problem of syncronization between java and the cpu's.
What can I do to resolve this situation
Thanks
