SunOS freeze-ups...

SunOS freeze-ups...

Post by kr » Sat, 18 May 1996 04:00:00



I'm running SunOS 4.1.3.  Sometimes, very rarely, the system freezes up for
a while, or lags very badly.  I have no idea what it is.  I do have some
NIS information:

   The system in question is an NIS master, has the hosts and passwd files.

   There is another system on the network that runs ypserv, but I have no
   idea why.

   I don't know NIS.

Anyways, this evening it happened, and I went to the console of the system
I suspected rebooted, that other one I mentioned running ypserv, and it was
running quite normally.  It had been up for 10 hours.

This may be a coincedence, but I did a kill -1 <ypserv number> on that system,
and about that time, the main master server began allowing telnets again.

Is there any help on this issue?

Thanks,

Ken.

I would suggest that you go to any reasonably well-stocked bookstore, and
buy Oreilly's NIS & NFS book.  It's an excellent start for managing NIS.
I'd suggest any university bookstore, or <free advert> Barnes and Noble.

1. Clock speeds and system freeze-ups...

I'd looked at some items in the newsgroups about segment violations and
"signal 6" and "signal 11" internal compiler errors having to do with
overheating Pentiums. I'd  had similar things happen, in addition to
the system freezing up.

The guy who put my PC together had the clock jumpered up to 120 MHz and
the Pentium is rated to 75 MHz.  Of course, he did this with my
knowledge,
and he wasn't trying to bilk me.  Anyway, it works fine with Windoze,
and Linux, until I really push it with some real multitasking, or try
to build a kernel. Basically, I was in denial: "CAN'T be the hardware!
It would've showed up a long time ago! Yeah, I KNOW it's pushing the
envelope already but..."

I'm stepped back to 100 MHz, and things are purring along.
So, lesson learned for me. It's not a black or white case whether
things will work when you crank up the clock speed...some spooky
things can happen.

Just though I'd pass this on.

Kudos to Thomas Lostaunau for hitting the nail right on the head.
