I have wrote about something strange i found. All the years of using BSD did not prepare me to solve this mystery.
I have a problem, did you find something similar? I am asking for suggestions where to look for, because probably no one solve this...
The question is:
Why it works flawlessly before?
I od not know why you want
uname
output, but here it is:
FreeBSD
Maybe you was thinking about something else? "uname -a" perhaps?
FreeBSD 10.0-RELEASE #0 r260789
No, there is no chance to change to 13 for at least year.
This is not the interrupt storm, because there are no messages about the storm in logs.
The
top
stats (for idle) show:
CPU: 0.0% user, 0.0% nice, 13.3% system, 0.0% interrupt, 86.7% idle
.
0.0% interrupt means no storm here. Am I wrong?
Of course i have looked at
systat -vmstat
but no help here. The most suspected is acpi, which is my only suspect. Why it was ok earlier?

This is simple storage. No cpu time consuming services.
Any ideas what went wrong?
Maybe someone have similar issue?
