Dears,
I'm having serious issues with a 15K main system controller. For some
reason, there is a tip process taking all the cpu load.
This morning and a few days before, I also noticed the hwad polling
daemon was constantly (for a long time) using 50 to 80% cpu time. Now,
only 2%.
The tip process is a process owned by sms-svc (at this time already
running in kernel space):
Regarding the tip hardwire, there is no smsconnectsc process to the
spare. On the spare, the console is not logged in on the serial port (no
console tty found while running who). There are currently no domain
consoles open.
I already did a reset of the spare system controller, from on the main
using resetsc, but no positive results. At this time, I think it's safe
to keep the failover enabled.
I found some document on sunsolve about high cpu usage on sunsolve, but
releated to fomd. Fomd seems to be running fine.
No error platform error messages, besides of the components which are
powered off.
Also Sun is trying to figure out what's going on, but no answer yet.
I also asked Sun the question if it would be harmless to run a truss on
an SC sms process (on the tip process). I certainly want to avoid dstops
on my production domains.
Advise or help would be very welcome on this (urgent issue).
Thanks in advance,
Kim DS.
Some output for you:
