Turn off jvm if you are not using it, it requires a lot of resources.

What are the problems that people have seen with the 4000 and 4 disk RAID5?
I've had no problems yet, but I don't want them either.
If the RAID 5 disk formats OK and works, am I in the clear?
As a complete Newb to this, what is JVM?
I appreciate the help. The snap I have came with 4.0.860 installed, I have no idea how much or what type of memory it has, but it has been running well since the new disks have been installed.
