Hello,
With amd64, I don't know why my system hangs (for a while) when I started another program? The hanging is about 2 minutes or longer depending on how long the other program is running.
Here is another weird thing I found, the jdk16 sometimes occupied a cpu with > 100% usage.
Here is my hardware configuration:
I have recmpiled kernel with SMP enabled.
Can anyone please advise how to resolve the issue with this multi-tasking problem in my FreeBSD system?
Thanks
Sam
