Hi there folx,
May be this is related to the problem I wrote here about
a couple of days before - mysterios system locks .. I don't
know.
Anyways , for 10 hours sytem here has percentage of system
time as high as 80 percent. No idle time.
The same time I can't find any resource consuming processes
on the system.
There about 17 users now logged in , and pstat shows ~11000
vnodes , while on the similar system under latest SNAP there
are only ~9000 of them and ~25 users on-line.
I suspect that the system moves now toword lockup because
of something ... probably some deadlocks in the kernel and too many
processes having to wait for the resource to be freed ?
How can I trace the kernel ? Is there a way to find the
reason for such behavior ?
System has QUOTAs switched on 5 FS, this is P90/128Mb RAM
Bustec SCSI 946C + 2 Barracudas ( 1Gb + 4 Gb). X11 is working
as well ( but it has nothing to do with it , since when
the system time jumped that high , X11 wasn't active).
Just in case some guru will read this stuff , here comes
the output from few commands:
Oh , f****k !
The system time've just returned to it's usual value,
as well as load average !
