Im just the oracle DBA but in the last 3 days 1 server I work with has had
some problems and was wondering if anyone could enlighten me.
This is a SunOS 5.9 Generic sun4u sparc SUNW,Ultra-60
First started with a cpu panic ?

Then May 19
But then I noticed the server load just doubled and the kernel was taking
50+% CPU.
I then found this in the /var/adm/messages
May 19 09:34:45 bad unix: [ID 882636 kern.warning] WARNING: interrupt level
12 not serviced
Any ideas on what the interrupt level 12 not serviced - could be pointing to
?
I shutdown the db and the server load was still high and the kernel was
still above 50%
We had to power-cycle to resolve this.
