The Microsoft Certified Systems Administrator (MCSA) certification
Program helps to validate an individual's ability to manage and
troubleshoot network environments based on the Windows Server 2008
operating system. because I have never had any idea of these things that
in this modern world we are going to be in that kind of technology filed
where we have to be best on our capabilities to success and stay at top.
I have been always a fan of innovation and new things in life so doin
these kind of courses like CCNA, MCSE and other certifications which can
not only help you for your future but also makes you unique in this
field as well.. so very happy to be part of this and want you guys to
also have a look at them because once you will join it and have a study
on these, you surely gona like it and appreciate the effort...this is
all what I can say, rest of you will decide. thanks!!!

Does this happen also with sun-java6?
You can check which one you're using with "sudo update-alternatives
--config java"

The bug is triggered when a CPU is offline. To reproduce, disable a CPU
or simply delete a file in the trace directory.
