Performance problem is mainly due to the fact that each zones share the same kernel. Thus when a software goes in kernel mode, the CPU time is not controlled anymore and the zone. So if there is a software bug during kernel mode, the zone will eat all the CPUs despite ressource control set.

Its no bug, it's the way zone are working.


Can you give a concrete example of how to reproduce this problem so it triggers the said kernel bug?

Are you hitting these issues or just making hypothetical claims based on the design?

The same could be said for WPARs too. That's why Sun offers different virtualization technologies as does IBM.

you can find the bug ID (6696124) in the thread but Sun removed it for security reason ....
"

The thread says a patch was delivered. The OP didn't post again so presumably it worked for them. Since they kept posting that they were unhappy, silence implies they are happy now.

I fail to see your point there. Are you saying AIX doesn't have bugs? I am sure a little searching will provide me with enough bugs where AIX boxes crash and reboot too.

If Sun hadn't removed the bug report for reasons of probable paranoia, maybe we would actually know what had happened and what the fix was. I assume that's what bug tracking systems are for.

If you're suggesting that people should merely wait until they get silence to assume something is fixed then I'm afraid that's rank amateurism at best, and that's reason enough to question usage of a technology - especially if you're paying for it.

Well ... i was still able to look up the BugID in sunsolve.sun.com . And by the way: There is nothing as too much paranoia in security. Just because you’re paranoid, doesn’t mean they’re not after you.
